I wish there were more categorizations, you know? I used to work in a video store and we... well, actually we weren't allowed to watch ANY movies on that giant flat screen that was facing us all day, but we tried to make sure they were PG-13 at the worst but PG-13 is so permissive these days that did little for us in terms of making decisions. Of course, now video stores don't really exist so it's a moot point but in my opinion, PG-13 is the death knell of cinema because everyone seems to be shooting for it, so old R-rated properties (Terminator and Total Recall) and what should be R-rated new properties are being diluted into PG-13. And you combine that with the fact that SO many movies are telling the same lousy 3-act stories, movies feel more boring. I just feel like if there were more rating categories, there'd be more holes for moviemakers to try to fill, you know?
