A cool Cartoon Network series with some fantasy violence

I think the series is really good. My oldest daughter really likes the character Radicles, a muscular alien who’s secretly a softy. The series has quite a bit of fantasy violence, but no blood or gore is ever seen. K.O. appears to really like his job at Lakewood Plaza, and he is a good role model. The series is rather entertaining, and my kids enjoy it, so it’s pretty good to me.

Powerpuff Girls proper remake

This is a wonderful show to watch with your kids. It has lovely messages that are really positive and fun for the whole family. It's really entertaining, funny, action packed show that your kids can enjoy. There are worse things like Teen Titan Go that your kid can watch that has way more inappropriate messages and visuals. This show is pure and is made with a pure heart since the creator has also worked on the popular show, Steven Universe. The animation is visually pleasing with great voice acting. I just can't praise this show enough.

Is It Any Good?

Our review:
Parents say (3 ):
Kids say (42 ):

This entertaining and positive series lets viewers follow the story of a likable kid with an active imagination and very clear goals. K.O. is sensitive and well-intentioned, but his drive to work hard and problem-solve, even after many failed attempts at being a hero, also make him a positive character.

The series features lots of clever moments, including funny one-liners and a memorable infomercial advertising Boxmore's services. These scenes may go over small children's heads, but chances are that younger tweens will find a lot to laugh at. Throughout it all, OK K.O.! Let's Be Heroes consistently underscores the fact that you aren't born a hero -- you become one.
