I will make it short: it is a nice, mind-boggling move, not more not less. We have seen people chasing each other on skies in the mountains already at least once in a James Bond movie and this is also not the first movie about dreams, manipulating peoples minds etc. The case is good, sci-fi effects are state of the art, but this is it. This is not a movie I will still think of in a week from now, a similar movie that really stuck to my mind was "Eternal Sunshine of the Spotless Mind", a lot less (if any) special effects, but very subtle. Still this is probably the best movie that is currently in the cinemas and it is worth seeing.
