I would have hated the Annoying Orange if I actually watched it. All I remember was watching part of the movie about 5 years ago in a hotel room. Lots of screaming foods and explosions...
But my least favorite Cartoon Network show is Teen Titans Go! They have a movie coming out this year, and it sounds awful. All the characters are obnoxious douchebags who all have their own issues. It's the ONLY thing CN airs on the weekends and they call it our new favorite show. After the movie comes out, I hope they cancel this show and never bring it back.
