Hilarious in Hindsight: PBS's Peg + Cat, debuting a couple years after The Problem Solverz ended, bears some remarkable similarities with this one; both are centered around solving problems and even have the characters acknowledge when a problem is solved. (Roba with the "Problem Solved" stamp in this show and a "Problem Solved" song in Peg + Cat.) They both even have unconventional art-styles. (Though Peg + Cats's notebook doodle-like look gets much fewer complaints directed towards it unlike this show.)
Mis-blamed: The show is often blamed for getting Sym-Bionic Titancancelled because it premiered around the time SBT ended. Cartoon Network picked up The Problem Solverz after it was rejected by [adult swim], long before SBT showed signs of ending because of its lack of a merchandising deal. The Problem Solverz was just the next show in line to be aired and had nothing to do with Sym-Bionic Titan, which was part of a different programming block altogether.
Nausea Fuel: This show is clearly not meant for epileptics.
So Okay, It's Average: Some feel that the only unbearable part is the art style, which in episodes like Time Twister, can easily give seizures. Everything else is just a run-of-the-mill adventure cartoon.
