Okay, so this show is not really good for kids to watch. First off, I'm going to say that if you or your child is epileptic or prone to seizures, DO NOT WATCH THIS SHOW. There's flashing colors and patterns everywhere, and just the way the characters are designed makes my eyes hurt.
The Problem Solverz has nothing inappropriate in it, except for the occasional bathroom joke. Despite the protagonists of this cartoon being a team of people who solve problems together, there aren't any positive messages or good role models. One of the main characters, Alfe, eats junk food all the time. There's cartoon violence like lasers and explosions, but no blood.
Now, is this show any good? I think not. The voice acting is bad and annoying, and the flashy, colorful visual style is disgusting. The animation is choppy as well. The plots aren't very good either. The "problem" is usually something really simple, and the entire episode is just fifteen minutes of filler stuff. The jokes aren't very funny either. Thank goodness this show is over.
