I just saw this yesterday, and I can confirm that this review is 100% accurate.
My theater was lucky and got it in it's wide release this past weekend. I'm a sucker for anything Clooney and I thought this was pretty spectacular. I'd rank it high in the best Clooney films, though nothing beats Up In the Air or Michael Clayton for me. I was a bit iffy on the Sid character at first, but he barely exists after his confrontation with Clooney. Not sure if it is something I'll watch again anytime soon, but it is definately one of the year's best.
