^Yeah I think a truly good film designed like this will cause you to question yourself. I'm trying to remember other films that work this way. It should be easy since they are always the ones that piss me off the most >.<
One thing I thought was poorly done thoug is character development and structure.. In the begining of the film it is about 'Inception' and the group they form, mainly Leo and the young girl. But by the end of the film it becomes purely about Leo and the other characters are all loose ends. Tough though because it was a long film as it and it was a complicated story to fit in a few hours. I think it could have done with 2 films, or they could have just taken out the other characters and made it so that he could operate soley, not a hard thing to do. blah blah blah blah blah....
Nerrrd... who goes for a second viewing?
I went to Avatar 3D twice in one week
