It really is amazing how standards and stuff have changed over the last few decades (sorry if I made you feel old just now).
But for those of you who don't remember/weren't born at the time, When Robin Hood and Batman Returns came out in the early 90s, there was a massive uproar because both films were not considered "Family Friendly." Batman Returns especially was considered far too macabre for kids, to the point where McDonalds pulled its marketing campaign for it after parents complained. Robin Hood was all criticized as far too violent and not "fun" enough for kids, especially by Roger Ebert for some reason.
But now? Both these movies feel so fucking tame compared the kinds of movies kids are watching now. Batman Returns especially feels downright CAMPY compared to the later Nolan films and especially The Batman. And I see plenty of The Batman toys and promotions out there at Target (RIP Toys R Us) but no large groups of parents complaining (I'm sure some are but they aren't being featured in news interviews like the parents complaining about Batman Returns were. Same with Robin Hood, the last two major films about him were far darker and more violent than Kevin Costner's.
