We usually try not to let our boys (15 and approaching 14 - 9th and 8th grade) watch R movies, but one of the things that we have run in to recently is the fact that so many movies from the 70s/early 80s are rated R because there wasn't a PG-13 yet (started in 1984). We wonder how many 'R' movies would be knocked down to a PG-13, and if anyone would ever go about re-rating some of the more popular movies. Examples from 1983 that are rated R are Vacation, Trading Places and Fast Times. Do those really need to be R?
On another side, my wife is semi-obsessed with Outlander (she will stay up until midnight on some Saturdays so that she can watch the episode when it first comes out onto On-Demand. She will let our daughter (approaching 11, 5th grade) watch with her, but only after she has watched, and watching an On-Demand version, so that she can FF thru some of the soft-core scenes.

I haven't seen the others recently enough to comment, but I am sure that the sex scenes and the abortion stuff would probably get Fast Times an R in our times too.
On that note, it's also worth bringing up how inconsistent the people who do the ratings are, and how prudish they are with the sex stuff too. I guess it's fitting to the thread and reflective of our culture as well. Violence w/o too much blood and swearing OK for pg-13, but nudity will bump it to R I believe if anything over a naked butt. I think you can drop 1 or 2 F bombs and have it as a PG-13, BUT you can only say "F You!", "F", etc.. If a character says "I
WANT to F you", that's gets an R even if it's the only F bomb in the movie because it's sexual. I think if there is implied homosexual relations that gets in the R rating too even if the rest of the movie is pretty tame. It's pretty interesting learning about the ratings system and how we don't know who does it and they have never come out with guidelines about why they do what they do. If you listen to interviews with directors or commentary tracks there are lots of stories about how annoying they are to deal with and you are forced to cooperate because the studio also wants to keep it at a certain rating for marketing too.
One that stands out was listening to Fincher on the Fight Club commentary talk about his battles. If I remember right, one issue was about how much a dildo on Marla's dresser moved when Tyler hit the dresser, and what she says after they have sex for the first time. I think the original line was "I want to have your abortion", but for some reason that was a no-go, and they allowed her line of "I haven't been F'd like that since grade school" in the movie and Fincher thought that 2nd one was much worse.
Long story short - I think IMDB is pretty good with the Parents Guide and it breaks down what is in the movie as far as violence, what swear words are used, what kind of sex and how much, etc.. I have looked at that a lot to jog my memory on some older movies before trying them with the kid. Like it was said above, there is a big difference even with the same ratings and something like Deadpool is on a different level than Die Hard or T2 would be.
