Horrible, horrible, horrible. Planet Sheen is, by far, the worst spinoff I've ever seen. With horrible characters, bland animation, and no originality, there is no redeeming qualities to this show at all. Jimmy Neutron was clever, funny, and original, everything that Planet Sheen isn't. When I first saw this, I was thoroughly disappointed. So disappointed, I lost interest the first minute. Without all of the spunky characters from the original series, Sheen, to be honest, is just an annoying idiot. This seems just like another time slot filler. It makes you wonder: Were they high when they made this? I loved Jimmy Neutron, but this...this is just a disgraceful waste of time.
