15+ Are you kidding me?!
I watched all episodes of this show just a couple weeks ago and there are definitely tons of sexual references such as "doing it, nailing, did it, done it, ex." But nothing worse then your kid is gonna hear in middle school probably even worse stuff then that. Almost every episode involves red saying "my foot up your ass" which is ment to be funny, there is cursing throughout the show mostly the words "whore, slut, bitch and ass" mostly aimed at Jackie who is supposed to be a spoiled rich girl in the show. No violence or gore. Hyde, Kelso Eric and fez are usually in a circle with smoke around it which is a reference to pot even though they never show drugs it is heavily implied, red is constantly shown drinking beer and there is underage drinking in the show. The later seasons like 7 and 8 get more realistic then funny with (SPOILERS) Eric going to Africa and leaving Donna and Kelso moving to Chicago it can be sad but in the finale Eric and Donna get back together and kiss. I think I mabye should have been a tad bit old to watch this but 15+ is insane I think 12+.
