Nice review; and I totally agree that it might have been much better if they made two movies, one specializing in dream experiments, and a sequel where they pull it all together to perform the Inception.
My biggest disappointment from Inception was that, for a movie that was all about being dreamlike, it did not feel dreamlike at all -- with the exception of the first 20 minutes or so, which I thought were fantastic.
I do applaud the film for attempting something extremely new and daring, but sadly I don't think it succeeded as well as it could have. Much of the acting fell flat, several scenes that had been foreshadowed once or more beforehand lacked punch when they finally happened, and the constant reminders of what was going on in each level of the dream became overly tedious. For having a selling point of being "a thinking man's movie", I felt like I was being spoon-fed far too much and was left little to ponder at the end aside from the obvious and mostly un-answerable question of is Cobbs back in reality or stuck in limbo?
Lucicka, might I suggest giving Primer a try? If you're into "realistic" sci-fi, an intelligently-crafted puzzle of a plotline, and excellent acting, then I don't think there's much out there that can top it. :)
