The trailer is so different than the movie, it tricks you. I'm being honest when it started I was really confused but then I understood it and got even more confused. It wasn't till the ending where I got everything. And I don't regret a single thing, now I have watched this film three times and every time it gets to me. It's so beautiful and impacts a lot. You will have to give it time, it can be boring at the begining but then it gets really better! I recomend it.
