OK, it's a movie with huge production values and a great cast and all that stuff. Beside those attributes, I found the movie too premise based and too math like. It felt similar to a time travel premise movie, where the buy in is important for the story (Memento). I didn't buy in. The talk and concept of different levels of dream states and manipulating the subconscious patterns of the dreamer seemed too formulaic and, even, immature.

Keep in mind, I'm writing this review a few years after seeing the movie. It was one of those films where I had to go out and see another movie to correct the experience and to remove the disappointment from my mind.

Good luck.
