Common Sense Note
Parents need to know that this silly (in a good way) spoof mocks villains, superheroes, and everything else it runs across. For example: Superwoman and man (in copyright-friendly disguise) argue over her girliness and his fear of commitment, and bad guys admit that they just wanted to make a lot of money so they wouldn't have to work. Most young kids won't get the satirical humor aimed at older audiences, but they can still enjoy the action and the ample physical comedy.
Side characters may indulge in some mild innuendo.
This is an action cartoon, albeit a semi-spoof. There are many explosions and crashes, and one character frequently fires guns, although never at anyone or with successful results. It's usually pretty clear that no one was hurt.
The Tick is determined that superheroes should rely on themselves, not weapons or gimmicks, and he believes powerfully in himself and his far-more-dubious sidekick. But strength and shows of force do rule the day.
