Interesting, because I've found imdb ratings to be the best because it's based on user votes.

Movie critics, on the other hand, seem to vote the complete opposite of regular viewers (and each other) to set themselves apart. Or voting some awful art house movie a 10/10 to signal that they, too, understood the high brow nuances that the groundlings could not. I end up agreeing with the user votes far more often than the critic scores on RT and Metacritic, and the user scores tend to line up with imdb anyways.
