re: Jaws is only rated PG?

PG-13 ruined so much....films avoided it as soon as the rating came out...just like they avoided X...so to accommodate and all the bad connotation's it carried, despite just being a rating higher than R - as you could have very violent movies with no nudity, rated X and therefore unreleasable, so the MPAA invented NC-17.

After that, films became all-in on PG or strictly R. The nanufactured middle ground became unacceptable to studios.
