Inception is one of the few science fiction movies from the past 20 years that isn’t ruined by a stupid ending (Moon is another). That alone is an accomplishment. It feels somewhat like a heist movie that takes place in people’s dreams, and then dreams inside other dreams and so on. That aspect of the storyline could have been confusing but it’s not. “Inception” isn’t epic science fiction, but it doesn’t fall into “sci-fi” silliness — so it’s worth checking out.
