Yet another... (Spoiler)
Bullcrap ending. No explanation in a movie full of reasons to give us an explanation as to what was going on.
So darn sick of this terrible trend in films to simply end without any sort of denouement. Sometimes it can work and let you "think" but in this case there were so many things that were out of the ether that an explanation of some sort was in order (a dream, she was dead, she smoked weed laced with a hallucinogenic... anything!)
No matter how good the film was the non-ending torpedoed it. Giving it a 2 and that is only because of what it could have been.
