At the end of the movie I was really surprised that someone actually stole the whole plot from "Paprika", an anime released in 2006.

Nolan shamelessly took story, characters and even scenes from Paprika - which goes way beyond "inspiration". Go search for Paprika on the net for yourself.

For the dialogues and directing: The first hour was just awful. That old shoe Leonardo and some other soulless characters talking and talking and talking. I just wanted to stand up and shout: SHUT UP AND GIMME A REASON TO WATCH!

And after noticing the whole idea was stolen, I really had a hard time not to leave. But I gave it a shot.

Nothing changed, three scenes switching all the time: falling car, dude fighting in hotel, a group of Chuck Norrisses fighting in snow. And that for an hour. Whee whee special effects! OK, but special effects should be the cherry on the delicious ice cream, not the ice cream itself.

Do yourself a favor and save your time and money. Unless you are into quickly changing scenes and super-mystical-pseudo-deepness with a bullshit ending (which are a lot of people).
