Good cinema, very good cinema. The movie is built well, played well and very well realized. For me, it presents a major defect: the lack of dramatic art. The movie is during 148 minutes but I think that would have be needed to have one hour furthermore to help the spectators to become identified more with the characters. I find that the heroes of the movie are not enough "worked". What I like in movies generally, it is when we have an ultra-precise idea of whom are the characters. In Inception it is not the case. We enter at once the action and the presentation, the psychology of the characters is just touched. I know that all the movies cannot have 220 minutes as "Once upon a time in America " where we follow the characters of their childhood in their death but there I find that it goes too fast... In the same way I shall have liked having a thorough explanation on the concept: who invented the "machine" which allows to enter the dreams? And when? How Cobb meets to live on this "business"? I find that this part misses cruelly. Following the example of " matrix " which succeeds in making credible a concept so complicated, "Inception" should have settled its concept with regard to the current reality. It would have allowed the spectators to become identified better with the characters. Chris Nolan remains a big director but honestly I expected in better especially after "Dark Knight"...
