True, Inception is a great movie, but it isn't a great "sci-fi" movie, and it should stop being tag-lined as such on just about every site, including IMDB. Part of my "slight" disappointment was my expectations of it being a "sci-fi" movie that will change my life, relate to my life, show me new concepts, and give me something new to think about from the world of film, much like many sci-fi movies have done. Did it do that? No, it didn't. That's not to say I didn't "enjoy" it though, but I would be careful about your assumptions of it being an "almighty" movie, because it isn't, and that everyone who doesn't think it is is "in the minority' and somehow wrong.
It's surely a GREAT crime/drama thriller movie, and personally, I didn't get "touched" by it, and I didn't sit around and "think" about the ending like some others did because I simply didn't care. See "Triangle" for a much better thinker film IMO.
Even still, I'll go ahead and say that 9/10 is a bit of an overrating, and it should continue to fall in the lower 8s were it belongs. This isn't Star Wars, Godfather, Shawshank Redemption, The Matrix, etc. This is a fantastically "contained" movie in itself, but nothing else.
Thanks Ralph for the review. I'll be picking this one up when the price is right.
