I don’t know if it’s a masterpiece but it does its role very well. Inception was the LSAT on big screen. With its many layers of thought and reason, you find yourself in a visual and cognitive labyrinth. I would recommend it, from a cognitive journey, it’s a masterpiece while lacking some key elements. The characters should have been developed more, the reason behind to whole process of mind access should have been developed more, how does this man obtain his wealth, how did he become who he is, when did mind access develop, etc? With no dates, time and explanation one wonders if it’s inconsistent writing or if it’s purposefully done to make you realize the whole… The movie itself never takes place in reality. I would totally recommend it but come prepared, or you’ll get lost in the idea of what you came for and end up in, limbo.
