Most people associate animation with children, but this isn’t always the case since animation is a medium rather than a genre. To make your life easier I will present you a list of cartoons and animated movies not made for all audiences.
Foodfight
Rock'n'Rule
Watership Down (don’t be fooled by the U rating it received in the past)
Padak
Helluva Boss
Bojack Horseman, Moral Orel, South Park, The Simpsons, Family Guy, Rick and Morty
Cool World
Fritz the Cat
Almost all anime shows are for adults. Ask the otakus and weebs about a show before you let your children see it, especially if you have little time to do your own research.
