Found this article at Answers.com.  I tend to agree with many of the films presented as being pretty strong stuff for a PG, or in some cases PG-13 rating, but the most surprising aspect of this list is how many of the films mentioned were either directed or produced by one Steven Spielberg.

8 Movies That Shouldn’t Have Been Rated PG

The one that most fascinates me is Jaws.  By today’s standards, the gore present in the film may not be that terrible (at least compared to some of the gory films that followed) yet the fact the film was given a PG rating is rather surprising.  We had full female nudity (although heavily in shadows, the shark’s first victim) along with some very gory scenes (including a severed leg sinking to the bottom of the sea).

It is rather remarkable the film received a PG rating back in 1975!
