They're the same freaks that make studios cut movies down to please those who are going to push the opening weekend box office. I read an article somewhere about the types that give these ratings and it really did seem that there were a few select theaters that the ratings were taken from. People knew going in that they were going to be a part of the rating so quite often you get people watching movies they normally wouldn't see but they're doing so because they feel having the power to rate makes them a critic or something. I haven't seen CABIN yet but perhaps it got a lot of "F" ratings from people who simply didn't like that kind of movie. I read THE THREE STOOGES got an A from young people but older ones gave it a C. Perhaps those older people just couldn't get the originals out of their minds or were some of those constantly upset that they were being remade. DRIVE getting a "C" is enough for me.
