I don't know what to write about this movie. I finished watching this several hours ago and I just can't stop thinking about it. This movie, as some people would call it, is a mindf*ck movie similar to Donnie Darko. I've starting coming up with crazy theories how the movie should be logically understood, but I am yet to find a reasonable and logical explanation for its ending. My effort might be futile, maybe it can't be explained; I'm not giving up yet!
