Dragonall has a decent amount of crude humor in it, with references to dirty magazines, exposing one's body in return for favors, as well as some shots of panties and other lingerie. Most of this is shown in a somewhat innocent light, but could be a sticking point for some parents.
That isn't the focus of the show, however. The show is mostly focused on the fighting, which isn't very bloody, but there is a lot of it. So if you have an impressionable kid who might try to replicate Son Goku's martial arts attacks, you may also want to steer clear of this one.
