Conclusion, movies that appeal to a larger range of individuals (not just adults, not just children) tend to be the more successful movies.
I agree with that, and so do the movie studios. That's why they cut and cut their movies until they achieve that non-R rating. I think we're more on the same page than we realize. My main point was that adults, by and large, do not go out of their way to see movies that are not rated R; that most of them generally do not have any moral hangups when it comes to violence, nudity, or bad words, nor do they even prefer movies without those things. An assertion I made from that point was that if kids did not exist or were not allowed to go to movies, the large majority of the top grossing films would be rated R (pretending that all of the movies would still be around. If kids did not exist, all of the G rated movies and most of the pg-13 rated movies would never have been made, imo, nor would movie studios need to try so hard for pg-13 by leaving so much material on the cutting room floor, which would result in more would-be pg-13 films ending up R). Another thing to consider is that kids' movies seem to be geared toward catering to all kids while doing that is more difficult when it comes to adults, each tending to enjoy a particular genre.
