This movie is widely criticized here because of its supposed lack of story. Indeed, if you've got your head stuck in the a** of the superhero movies and cellphone culture that Iñarritu is vehemently complaining against with this movie, it's got a definite lack of action. But, if you can appreciate a bit more subtlety and have some patience, can tie up some of the loose ends by yourself instead of having everything spelled out for you, then you'll see this movie is a nice little puzzle. It shows an actor that is depressed, passed his high days, going insane- some of the scenes really blur the line between reality and the main character's imagination. Definitely not an easy watch, but both the story, camera-work and acting have been worked out in detail really well- however none provide the viewer with everything on a silver platter. Watch if you're in a mood to think, not if you want an easy cheesy comedy.
