I personally would say it would be kind of ridiculous to try to argue that critic's and other's opinions on films do not at all play a factor in determining one's choice of films to watch. It's not like you go to the movie theater or go to the video rental store and just choose something at random. And yes, although subject matter may play a part, it cannot be the only deciding factor.

I admit, I've seen certain crime-related films despite their bad reviews, just because I knew I would enjoy it for its subject matter. Once and a while, I disagree with the critics, and find something I like in a film that was generally panned. But I still look at and consider the critics opinions before I choose to see these movies.
