Terribly boring. You start out with the expectation of a big story. You're halfway thru the movie before you realize no big reveal is coming. It's as if someone was making a documentary, waited until the deadline, and then just mashed several chaotic scenes together.
There are literally no answers to any of the story other than one character's connection to Clooney. There is no explained, no resolution, no closure.
I was angry at Clooney at the end for feeling like he deliberately wasting my time.
