It really depends on the movie. I see your point about it sometimes being a lazy way to cover up for poor acting, or just to go for shock value, but consider "Die Hard" - the word "fuck" (and variations on it) is used 50 times, mostly by John McClane. I think that helps contribute to the atmosphere of his being a regular guy who's in way over his head, doing his best to survive in an impossible situation. Either way though, I don't think it should be the ratings agency's job to enforce artistic quality. Either movies that lazily use profanity will fail on their own lack of merit, or they'll succeed; in which case I would argue that the public is getting what it's asking for. Side note: I think it's poor form to lead a comment with "I know this will get downvoted" or "time to burn some karma" etc. It comes off as a pretty annoying attempt to psychologically manipulate readers.
