Clarence and The Amazing World of Gumball are the best shows they have.
Johnny Test, however, is the devil. I have a hard time believing that it actually gets ratings good enough to justify it continuing to air after so long. I'm not sure what's up with that. Nine years and seven seasons of this abomination...
To be fair, when the show first came out, (Season one. Exclusively. Not even all of season one, it was that short lived.) it was decent. (At least, to me.) (The hand drawn animation was actually cool.)
However, it was butchered almost instantly afterwards and became the mess we knew today.
Teen Titans Go can just suck a big one.
