Too many people have this mindset about reviewers, as if they hate anything mainstream and only latch on to a handful of indy flicks that are impossible to understand. All too often, it seems like people avoid even reading reviews because they have the "I'll decide if it's good or not for myself" state of mind. Nothing wrong with forming your own opinion, but avoiding reviews is a bit silly.
I check reviews (primarily Ebert) on the regular. Not because I can't form my own opinions, but rather, they help find the diamonds in the rough. With the sheer quantity of films being released every year, it's easy to miss the less promoted ones. Checking out the reviews can alert you to these films and at least pique your interest on other ones you may have not considered checking out before.
Citing Ebert has become something of a pattern for me. Not because I can't form my own opinion. The guy just knows what he's talking about. Whether he likes it or not, he's always there with the reasons he came to that conclusion.
Reading reviews and/or sharing similar opinions with reviewers doesn't make you some mindless drone. Just more informed. At least in regards to the former, anyway.
