I think you guys might be looking back through rose-colored glasses here. Most of the movies mentioned here, while some of my favorites from that era, are far from clean, wholesome family fun. In fact, as my kids have gotten older, my wife and I have rented a lot of our favorites from that era to watch with them. We've both come to the conclusion that the motion pictures rating system is far stricter today than it was in the 80's. I've seen PG movies that would probably get at least a PG-13 or maybe even an R rating today. Heck, someone mentioned "Planes, Trains and Automobiles", but that was rated R. Adventures in Babysitting had some fairly strong language (such as "f--k," "s--t" "son of a *****," "*******"), there was the "***** breath" joke in ET, the list goes on. If the word "idiot" makes you uneasy, 90% of the movies mentioned so far would almost certainly cause you concern. And sadly, a LOT of these movies are pretty stupid. We may have enjoyed them as kids, but watching them again today, from an adult perspective and having seen a lot of more quality movies, quite a few mentioned here just don't hold up, and I think kids wouldn't really like them, either. And, I'm not saying that today's kids are too jaded and won't enjoy a movie without sexual content, profanity or violence, its just that these aren't particularly good movies and today's kids have access to much higher quality movies than we did growing up. Seriously, stack up Pete's Dragon against Wall-e.
I guess the point I'm making is that there are tons of family-friendly movies today, and that I would argue today's family oriented movies are MUCH better than they were 20 years ago and as parents, our choices are much better than what our parents faced.
