Loved it, actually.

Swiss Army Man

A man stranded on an island tries to commit suicide but gets interrupted by a corpse washed onto the shore. He befriends him, and so begins the surreal journey back home.

^Loosely quoting here, really.

Alllright, let's get this one going.
I've just finished it ten minutes ago, and my mind is fuzzing up with all those stuffs in the film.

And before you go on, lemme warn you, there are perhaps spoilers in this and I strongly recommend you watch it before reading this.

First off, Swiss Army Man is not a movie that you would want to watch if you like straightforward, traditional and logical things. It is whimsical, odd- very, very, odd- hilarious to say the least, exotic, daring, and all in all rather beautiful.
It doesn't provide actual closure, but it isn't open-ended and thought provoking like Life of Pi or other well-known movies that provide endings that are somewhat satisfactory in how it provokes thought.
Rather, it has crude jokes inserted that causes most viewers to detract from the main essence of the film. Those very same jokes however, are really moving and beautiful when it comes down to the meaning of things, and I do agree that this movie is ultimately about celebrating your own uniqueness- thereby making it one of the best films of this year.
Personally, I found it amazing how the corpse is used as a mere prop with flexibility to cater to every situation. When the protagonist requires emotional support, Manny becomes a friend.
When he needs a reason to propel him forward and something to fill up his mind so as to distract him from the messed up thoughts and emotions in him, Manny acquires the role of a young child alike to a new born, and the need to fulfil Manny's need for knowledge forces him to teach and therefore put his burdens aside for the moment.
When that succeeds, Manny 'ages' and becomes a friend, one who does things that are considered gross in others' eyes- obnoxious farting, and so on.
He talks about masturbation openly, both with the innocence and curiosity of a child and the simplicity of honesty. Likely, Manny speaks of Hank's darkest thoughts as well as everyone else's forbidden thoughts, and sheds light on them. By doing so, Hank projects his deepest darkest persona upon Manny and thus succeeds in avoiding responsibility of his own thoughts because it isn't him who is speaking, but Manny, and this helps him face his most hidden sides as an outsider of the entire situation would.
Simply put, he runs away and faces himself simultaneously through the mouthpiece that is Manny, the corpse with no definitive personality.
As the film goes on, hints dropped at Hank's past begins to be explored, and in the same way that masturbation is. To me, it is a metaphor for the taboo, and people's avoidance of talking about it. Whenever it gets too hard for Hank to face things, his and Manny's roles are swapped, and Manny becomes Hank whilst he plays the role of the supportive friend.
At first a simple humourous cross-dressing scene, it later progresses on to signify, in the bus scene where he role plays as the crush that never knew him--- how Hank is truly the master at bending reality to his will, and how he is capable of escaping into different personas in order to mould things to his ideal, or to face the reality that which was not ideal.
The fact that Hank has complete control here is constantly being parodied and subtly made fun of when he takes off his wig the moment  Manny digs into his past in front of his crush, which he imaginarily role-plays. Interestingly enough, Hank both knows that all of it is in his head, and thinks of it as somewhat real.Once again, it starts off funny but quickly gets heavy while still retaining the beauty of it all.
However, he slowly comes to terms with things as the movie goes on, and it isn't exactly the remedy that most of us are accustomed to but a mere way of peeling his character open for the audience to see. As he approaches civilisation and therefore help, he settles down to a conversation in which he fantasizes about staying there forever- And very unsurprisingly, Manny agrees with him. Before this, Manny has been both a great companion and the voice of reason or friendship. He saves him in all senses, from perilous situations and his own grief at the depressing events of the life that he has led.  Here however, he doesn't say what is politically correct, and doesn't remind Hank of the purpose he set out with (which is to escape the deserted island and get help). In a way, he plays the ideal partner that provides the emotional support in the form of words you most want to hear when you're lost and confused and all messed up inside. It's all very sad, but Manny could have been a mouthpiece here once again, parroting Hank's thoughts in the warm manner that Hank craves- friendship.
Hank seeks solace in Manny, be it through facing himself or running away from it or simply needing a place of fantasy to live out his desires for once.

I loved the film up to here,
But it went slightly downhill with the mixing in of reality and how harsh it all is.
What starts off as a theory of Hank possibly cooking up an imaginary friend  in Manny from the holes in his heart or the desperate desire for insanity not to claim him when he's all alone in the forest quickly escalates into insanity, which is a fine line away.
One thing I didn't appreciate was how the media was brought in, and how that alone ridiculed him and therefore the beauty set on the table by Hank and Manny's fragile bond, however 'illogical'. Hank is made to go on camera, and other unnecessary elements are brought in. It felt like a beautiful star-lit picture being tainted with black mud, because the peaceful sanctuary that Hank found in Manny, the companionship, love, acceptance, strength to go on... All became exposed to reality and how it screams logic. The spotlight leaves that bond acquired thus far, and goes straight on to insanity.
The sacredness brought about by the abstract feeling from the film is eradicated,
And Hank's arrest, his crush's reaction to him is as of disgust and shock, all accentuates that.

Then Hank does what some of us would really like to do-
He remains rooted in his belief that Manny is truly alive and he tries to repair that shattered bond- shattered by the bringing in of outsiders- and tries to convince the masses of that.
Of course he fails, and this only further breaks down the delicate balance between insanity and fragile, upsetting imagination used for comfort and solace established from the beginning of the film.

The rest of it, to me, is merely Hank winning over reality yet again with his imagination,
And he either sets both himself and Manny free by letting Manny speed off into the ocean with his farts of cannon, or he simply manages to 'prove' to everyone that Manny was indeed alive. This is a rather feeble attempt at an open ending in my opinion, and I think of the second option as more plausible.
Thing is, Hank once again shatters under the pressure of having to face reality in the form of other people's reactions (and therefore confirmation) of his insanity, and he now whisks himself off (signified by Manny speeding into the ocean) into the land of his own mind and fantasies, this time taking other people's reactions into account because they help strongly in alleviating the grief and stress that he was that close to crumbling under.

All in all, Swiss Army Man is an uncommon movie bursting with creativity and originality. Due to its rarity, it is very easy to get caught on the web of the explicits, such as the plot device of farts and fart jokes, and fail to see past all that to realise just how great of a movie this is.
It is simply an innovation, one dark, slightly silly, slightly ridiculous, and slightly mad, but nonetheless underlined with interesting takeaways and beauty.  Wrapped up in carefully constructed ambience and both crude humour and subtle parodies, the film utilises really good music that is used in time and in appropriation to the moments and dialogues, thereby highlighting all of that rather well.

Perhaps one fatal flaw is its failed attempt at something overly ambitious like meshing reality and fantasies together, and an open ending which doesn't sit quite right, particularly so if you include how they identified Hank as Manny and vice versa.
It attempts to complicate things, and while this swapping of identities may be a confirmation of my theories earlier, it just seems so... excessive.
There were moments which could have been more subtle, such as the 'I had a thought, which led to other thoughts...' , and there were moments which could have been much slower so that the audience can actually catch what the jam packed glimpses were about.

I really enjoyed this movie, but I wasn't a fan of the ending.

And to loosely quote again, it is rather amazing, but when you try to explain it,  it all falls apart..  til you actually see it.

My review's pretty disorganized and all over the place, but I hope I've at least interested you in watching that movie if you haven't already. This is the first proper movie review that I've ever tried my hand at, after all.
Or perhaps
I should just stick to the extremely vocal comments that I've been doing for past posts, since this one right now exposes too much of my (lack of) literary talent.

And yes, the sexual innuendos in this might make you reconsider watching it with someone, particularly one who judges something he is unaccustomed to. The humour is just fantastic though.

And I think this just might be my new favourite movie.
