What is your theory on the ending of INCEPTION? ((((SPOILERS AHEAD))))?

Well I think the end of the movie just left it open to your own interpretation. Because we saw that the top was kind of toppling over, but never saw it completely fall, so nobody really knows for sure. Personally, I think that he was stuck in the dream, because he kept saying to Ellen Page's character, don't dream about memories, because then you'll confuse dreams with reality, and I think that's what happened to him. He couldn't tell the difference between dreams and reality. Yeah, at the end, it was all Cobb's dream, but I'm not sure about the acknowledged glances either. I wasn't sure if they were all in the dream too, or if the "characters" were just projections in his mind. Oh man... that movie was just AWESOME!
