My only real problem (and it isn't enough to make my son stop watching) is a fairly high level of sexism in the shows. For example, Fred is constantly giving Daphne grief for being "danger-prone Daphne" whenever she falls into some trap. But he falls into traps as often as she does, and no one says a word to him about it. I know this is pretty much a reflection of the general attitude from the 70's, but if you watch more modern shows, there are more strong and stronger female parts. Even the more recent Scooby shows have less verbal sexism and Daphne and Velma stronger. Otherwise, we love the show. My kid likes more involved plots and he loves spooky stuff, but I refuse to let him watch most of the stuff he would prefer because of violence or bad social situations like drunkenness or smoking. Scooby fits the bill perfectly.
