The concept of Inception is a very appealing one, and the film is wonderfully inventive. It's also not as confusing or effects-heavy as some have said - the story is actually very well constructed. That just makes it all the more frustrating, because Inception has some very hard to define flaws that prevents it from being a truly great movie - most of all the very uninteresting characters. It's not exactly that they're flat - they're all convincing enough and the dialog is fluent enough, but none of them deserve any true emotion or interest from the viewer. It's a good movie by any measure, and yet - like every previous Christopher Nolan movie - stops just short of being a fantastic one.
