I have to say, I liked this movie. It is pretty interesting, and is those kind of movies that will keep you thinking about it, even hours after you've watched it. The plot does seem a bit blurry through out the movie, but as the ending approaches it becomes more clear, what is going on. It was small details that at first will pass by unnoticed that will let you later realize how much they were hinting what was coming.
I do have to admit that I wish they would've give more in the ending.. although I'm not sure yet how much more they would've been able to push it, because in one hand, it was a definitely explanation to everything that happened, but than it keeps you waiting for more. This movie is a must-see .. if you liked Donnie Darko or any other movie that is not to obvious and actually gives the viewer a chance to analyze the plot as to just making it too easy and obvious to the audience like most movies do now days. overall... thumbs up for this.
