There are multiple reason to watch this awesome movie, first of all its a nolan film, Second its cast. Dicaprio, Joseph Gordon Lewitt all did a stellar performance as usual.
I dont want to take away anything from the movie, but the thing is, one have to watch this movie atleast twice to understand the concepts in the movie fully. The depth and the tiny details in each scene is so vital, that you cant lose any concentration at any moment.
And Nolan of course, a master behind the camera, The visual effects are awesome and imaginative, and best of all they do not bring down the movie’s quality one bit, rather it makes the movie more fascinating to watch. The cinematography is absolutely, beautifully shot, so we can see the action and emotion in all their glory. Production design is top notch, with terrific design of sets and locations.I have seen the making of this movie which describes what level Nolan have tried to make this film as realistic as possible
I would give 10/10
