Possibly the most boring and most confusing film ever made?

I enjoyed it. The performances especially Clooney kept my interest because the story was confusing and did require your full attention.

A difficult film to watch. Confusing? yes. Boring? I have to say no. Certainly very challenging, a film that requires your utmost diligence.
I thoroughly enjoyed it, very compelling film.

I really enjoyed it. It does require you to really pay attention, so its best watched when you're in the mood for that kind of thing.
