Technically amazing. Stylish, stunning, handsome - every positive descriptive word for great visuals you can think of could describe this movie, even the story is very interesting, however this is where it is left down.
Sure it is masterfully told as to be complex, yet not confusing, however unless you have fully realized characters in your film, they idea, no matter how brilliant, is going to suffer.
Every single actor in this works extremely hard to add depth and fullness to their roles but each one of them fails. No amount of visual pizzaz can hide the fact that 'Inception' has no beating heart.
However, it is technically amazing.
