The film stars Leonardo DiCaprio [fresh off of an different psychological film: Shutter Island], Ellen Page [Juno], Marion Cotillard [La Vie en Rose and Nine], and Joseph Gordon-Levitt [(500) Days of Summer and The Lookout]. The concept of the film is all about existing in a dream space. Basically the idea that people can enter and share dreams, then inside dreams they can enter dreams. The dream within a dream theory is pretty powerful, and is fully explained over the course of this film. At almost two and a half hours it is a commitment, and I highly suggest that is be watched in a single sitting.
So did I like this or The Social Network better? That gets into a gray area, because they both get the illusive 10/10 for completely different reasons. This is the type of film I could watch again and again. Social Net. is a film that I found myself lost in on first watch, which doesn't necessarily translate into a great second viewing. Nor do I feel that I must pick, since I gave them both 10's. I fully expect The Social Network to win the Oscar, I don't think an action film like this has a chance. If you asked me which I would rather have in my personal collection and would like to go to the theater to watch with you right now... I'd say Inception.
Vote: 10/10
