I just finished the movie about 10 minutes ago and I will try to find some words to express my feelings about it (which is kind of hard).
At first, I want to make clear that this movie isn't for everyone. You need to have the right humor to like and understand it (Is there even something to understand behind the movie, I'm not sure).
There isn't any specific story, what you should already know after reading the summary, the movie has an overall little plot that follows trough it, but it's not needed.
It has 3 or 4 main "stories" which are put into these 21 short episodes. Between the episdes they play some short cuts from the opening speech and from some episodes.
The movie is divided into two parts named "Side A" and "Side B". After the first part of the movie you got a 3 minutes long "Intermisson", to prepare for the second part (Drink or eat something). When you thought the first part was wierd, the second one is much more wild and bizzare.
Also I want to add, some of the scenes are may inapporiate, kind of sexual and nasty for you, so be prepared for that.
The actors (in my opinion) did a good job. I personally totally buy their acting and I'm still not sure how you even can do such things and still being serious while doing it. Really, how?
There wasn't really any music to name, except some music for specific scenes to dance or relax (?) to.
In the end, I would watch the movie again, with friends who haven't watch it now and wait for their facial expressions and what they think about it. I'm already excited for it!
So it's a overall good movie, when you can deal with the given scenes and have the kind of humor the people behind the movie have. Give it a try, when you're interested in it.
