I cannot tell you how excited I had been to see this movie since May when I heard about it after being out of the US for so long. "Leonardo Dicaprio might make something less problematic than Blood Diamonds with a scifi tag-on to it? I'm in."
This movie has been my main topic of conversation for the past week. I had heard that the most negative review it had gotten was that it was "confusing" and "hard to follow," but that, on the otherhand, it was supposed to feel like a "dream-like state," "a dream within a dream," and like, in effect, you're left within a "dream-like" open ending to decide for yourself if what you see at last is real or still apart of the dream you went through with the characters. I saw it, now twice (once regularly, and once in IMAX), and can say that it actually is one of the best scifis I've ever seen. Besides the surprisingly good acting (which usually struggles in the scifi genre to me) with a brilliant cast (you have before you a Third Rock follower, born and bred) and amazing sets and effects to make it feel more real than you would expect as a viewer, it reminded me of how I felt discovering the plot of "Donnie Darko" years ago, with more clues and a faster pace that kept me guessing the entire way through.
Also noting what I perceived of as intense sexual tension between Tom Hardy and Joseph Gordon Levitt that kind of surprised me (not quite sure if Nolan had that in mind, but it made the movie more interesting for sure), I suggest it to anybody who wants to see something that will make you think about reality: who's to say that dreams are only dreams?
