I'll go and see anything that looks half decent from the trailer/synopsis, as a reviewer myself i try to avoid reading reviews before seeing a film so as not to be influenced in my opinion and overall verdict.
You'll find that you enjoy films a lot more if you don't actually know much about what it's like beforehand. As an example, Matrix Revolutions got critically panned, but because i didn't pay any attention or read any reviews, i actually quite enjoyed it, as opposed to criticising it all the way through because of what some harsh critic has said. Same goes for all the Star Wars prequels (except Ep 1, that really was just plain bad, lol).
