Inception

[McLovin']

EDIT: Except there is ONE thing that completely discredits this theory (SPOILER)and that is the fact that in every dream sequence Cobb is wearing his wedding ring. In every reality sequence he is not. In the final scene the ring can be seen.

Are you sure about this? Because other people are saying that he is definitely NOT wearing his ring during the final scenes. And if the ring serves as the audience's totem, then it means the ending was (SPOILER)reality.

Oh heh, I was actually just making an assumption. Because I just assumed it was reality and that he would have been wearing the ring. Hadn't fully thought about that the movie could have really differing views. Sorry
