I'm not going to even go out on a limb here. I believe that I've adequately found evidence to back up the following statement: the OP's opinion about movies is pretty poor. There are a lot of movies that *I* don't like, but which are outstanding movies. In fact, there are movies that you couldn't pay me to watch again. But, I'm not stupid enough to think that because the movie doesn't match the style of movie I enjoy, that means it's a bad movie.
