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.)
At the end of "Time Twister", Alfe gives Roba a hug and Heart Symbols appear around them.
In "Funny Facez", Alfe says, "I love you guys," and then gives Horace and Roba a kiss.
In "Badcat", there is a very brief shot of Roba and Alfe Sweetheart Sipping in the casino.
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.
The Scrappy: Not that any of the characters are that interesting to begin with, Alfe is, by far, considered one of the worst characters of the show. See Designated Hero and Creator's Pet for more details.
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.
