Killing me with cleverness

I am not precious about Inception. After sitting through six hours of the movie, I came away feeling a little daft. I don't like movies that do that to me.
Inception is a bit like the bore at the bar who just can't stop trying to prove how clever he is while all you want is a barf bag.
I am a big Nolan fan but he should be locked up in Gotham. You let him loose in the real world and he can tire you with his cleverness.
