Terribly cheesy voice-acting, cliché villain, horribly written characters, and humor that relies on fart jokes all combine to make this lame show.
Honestly I don't understand that love for this whatsoever and the fact that someone here actually compared it to a masterpiece such as Courage the Cowardly Dog is ridiculous.
Everything apart from the animation is terrible in this show.
It's basically the Sonic Boom for Disney, relying on crap humor, a cliché terribly written plot, and flat characters that they constantly try to add depth to but honestly the characters are irredeemable. The show pretty much relies solely on the edgy teenager cliché for the characters.
Basically everything that's been done in this show was done about 10 years ago but was done far better back then.
