Where should I start? It would be better to get straight to the point. Firstly, despite the idea is brilliant, in other words, generally the story of the movie is brilliant, ideas don't make a movie great as just complicatedness doesn't make a movie good. By this movie, personally, I have understood that Nolan is not "my director". The Dark Knight was also a serious disappointment for me and Batman Begins was just a summer blockbuster (Following and Prestige were very very good) As for Inception, the biggest flaw of the movie is the movie is lack of heart and soul, in other words, it is cold. The characters are cold, the atmosphere is cold, the reactions are cold, because they are in dream? Well, I don't think so. It causes what then? I didn't much care about the intrigue, couldn't identify with the characters, so the most important problem of the movie is its dramatic structure. The second is the "dreams" itself. You know, the agent of dreams in cinema is David Lynch. Why? Because he shoots creative, intriguing, sometimes meaningless as it should be and surreal dream sequences. The dream sequences in Inception can only impress the architects, mathematicians and some businessmen (because there are a lot of men in black suit) It is because like his approach towards Batman, he sticks to reality. Despite the visual effects are jaw dropping, "the street bending" scene is my favorite, it doesn't help much. By the way, honestly, I couldn't understand the trick of Ariadne, for example, is it planned or impromptu? If the point is impressiveness, well I was much more impressed by Sucker Punch for example which has been exposed to harsh reviews. The movie also has not any dramatic twist, epic scene (except for a few moments) or real mystery which had been all necessary in my opinion. Can we say that the movie was low key? Thirdly, some, may be many action scenes seem pointless and ineffective. Especially the "snow" sequence. It was too long without real entertainment or excitement. There is not any problem with the cast (except the fact that in contrast with the majority, I think that Leonardo Di Caprio's performance in this movie was just good, not his best performance so far, it is nothing, for example in comparison with What's eating Gilbert Grape!), but it is a bit disappointing that Nolan often uses the same actors in his movies. A note: Michael Caine's character might be a tribute for his character in Children of Men. If you ask me, the best part of the movie is the "train scene" It was the only scene that I was dramatically involved and got excited. The "gravity" sequence was just interesting. I didn't find it epic. Finally, about the plot, I didn't find the starting point creative, brilliant or exciting. I mean the concept of choosing a businessman for inception, weren't there better options? In other words, the main story was too poor for the concept. However, if we consider Nolan's style, to tell a story about the world of business, might be exciting for him. However, if we consider the hype, the rating, the reviews etc. it seems that Mr. Nolan has deluded audiences again or we have been incepted.
