Inception isn't exactly surreal, but it feels that way, with all its layers of action and non-sequitur switches from one scene to another. I was mostly bewildered, in spite of paying really close attention to every clue, every scrap of information the film makers provided. I do think you have to see this more than once to follow what's happening. It's a classy movie, well acted; Leo is very good, a mature actor now with great skill. Ellen Page's role was pretty thankless--her character is there chiefly to explain the mechanism that drives the plot--but she's a talented lady, and the remaining cast were fine, though Ken Watanabe's speech is hard to understand. The story raises ethical, even moral, issues that no one pays attention to; in that regard, it has an underlying sleaziness.
Inception is a strange mix of special effects and standard action fare: car chases and crashes, shoot-outs, fistfights, spectacular explosions, collapsing buildings, zero-gravity sequences. Parts of it feel like Mission Impossible stunts, and other parts look lifted from Casino Royale, the James Bond flick where the house on the Grand Canal comes down. Some people in the theater applauded at the end. Inception will likely appeal to the crowd who went for The Matrix, Eternal Sunshine of the Spotless Mind, Minority Report, Memento, and Donnie Darko.
