"What have we done to deserve any of this?"

Rating: 8/10 (29 June 2016)

To answer a few of the questions that are out there.
1.Is this movie just a collection of random things?
No.
2.Does this movie have a proper story with a beginning and an end?
Yes, most definitely.
3.Is it actually trying to say something?
Yes, but you might not want to listen, because it's kind of depressing. People usually don't like sad things.
4.Is it just like those quote-unquote actually good movies that play with realities and use unreliable narrators in surreal scenarios like ESOTSM, "Being John Malkovich", "Waking life" and others? (I also like these three)
Yes, just like "The illusionist" and "Prestige" are basically the same.
Just because they're similar conceptually (very broadly speaking) doesn't mean they're the same. It's still a completely different story.
The movie is neither a really deep philosophical one nor is it meant to be a hardcore scifi in the generic sense. It wasn't meant to be a study into the problem of choice in a deterministic reality and even if it was supposed to be something like that, i don't think that's the reason why you should watch it.
I think what it is about is the regret of living a single life. We are bound in these decaying bodies for a brief period of consciousness and nothing that we experience we can completely trust to be real, whatever that means, but we just seem to go with it because why not!

If there is free will and our actions truly determine the course of our lives the question that the movie asks is which choice is the right choice? It's asking the question which life is the right one. The answer it gets eventually is way too simple. In a way it's not even an answer at all, which is painfully annoying. But i think i can understand because it is the sort of question that has no right answer. It's something that you can't really do much about except find a way to live with and that it helps us do.
So basically for the majority audience, you are about to be introduced to a sorrow that wasn't there before but they'll also give you a way to live with it so i guess it's all fine in the end.
To watch this movie is a choice just like any other. Whether you willingly make that choice, whether that choice is made for you by a God or the invisible forces of nature, or whether it is a random outcome out of the infinitely many possibilities that could have happened or did happen, the choice is still there. Even if it has already been made for you, it had to be made.
The story is intriguing, the visuals are captivating, the characters are complex and nothing is there just because. It's not perfect at all, but it's a really good movie that deserves a watch.
