Awesome Music: The Roba rap at the end of "Magic Clock". The colors.
Hell, the soundtrack of the show is actually pretty good and of the few positive aspects that most haters can agree with.
Critical Backlash: Started receiving this years after its cancellation with people who don't outright hate it finding it passable and with some people even praising the highly divisive art style as being unique compared to most Cartoon Network shows airing at the time.
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: This show is often blamed for getting Sym-Bionic Titancanceled 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 not meant for epileptics... or most autistic people... or, really, anyone with a strong hatred for insanely bright colors and annoying music and sounds. Or, anyone who isn't colorblind.
Unfortunate Character Design: Alfe is supposed to be part-dog, part-anteater, and part-human, but instead he looks like a giant pile of poop with a face.
Unintentional Uncanny Valley: Given the surrealist nature of the show, it's uncertain exactly how unintentional this is supposed to be. Either way, one thing's for sure is that the character designs are absolutely frightening; everybody is drawn with freakishly bulbous eyes, giant lips that look more like hot dog buns, and have various levels of realistic detail (like visible irises and wrinkles) that clash badly with the choppy animation and DeviantArt-esque art direction.
