How about movies before the Hayes code was eliminated? I think around before 1968? I just felt that Hollywood back then had more creativity before the gratuitous sex and violence started getting out of hand. I'm not a prude by any means just thought that Hollywood had much better quality of movies from that particular era.
For example I just got done watching the 1945 version of the Picture of Dorian Gray with Angela Lansbury and thought it was much superior than the newer 1970s version which had copious amounts of sexual matters and drug use. You know what they say, sometimes less is more. The '45 version just hinted what were the sins of Dorian instead of showing it like the 70s version, surprisingly it's also rated much higher by critics.
