i think it has more to do w/ clooney sort of being typecast in 90% of his roles. from dusk to oceans to o brother to burn after reading, dude always seems like the same guy. nothing different about this film really. not saying clooney's a bad actor - he's not - but for some people i guess his personality didn't mesh w/ the overall tone of the film.

i personally didn't have an issue w/ dude but could see why someone would.
