Cool movie that started a okay show that ended as it was getting better. A boy genius who invents stuff that does not always work and gets him and the world into deep shit (e.g. aliens kidnap parents, meteorite, evil pants, evil sales/nano robots) and usually ends up saving the day only to do it all over again. Has two funny but weird friends Carl and Sheen, has a funny yet retarded father, Hugh. Rival is Cindy who secretly loves him but picks on him to hide it.

Despite what many people say, this show/movie was NOT rip off of Dexter's lab. The only thing similar is both shows focus on a boy genius. Parents are different, rivals are different and Jimmy has actual friends!

To those who keep complaining about breathing in space, IT'S A FREAKING CARTOON ABOUT A GENIUS KID WHO INVENTS STUFF! GET OVER YOURSELVES!
Jimmy Neutron : Gotta blast!

Carl: Llamas!
Sheen: Ultralord is a action figure, not a doll!
Cindy: Nice invention Neutron!
Jimmy's Dad: Bring on the pie!

James Issac Neutron, or Jimmy Neutron is the 10-year-old boy genius star of DNA Production's CGI animaged movie and television series.

Airing on Nickelodeon, Jimmy Neutron follows the adventures of a boy genius, from Retroville, Texas, who, with the companion of his swiss-army-knife-like robotic dog, Goddard, can invent himself out of any situation. Unfortunately, his inventions don't always work, and it's up to him to save Retroville from pandamonium.

Jimmy has two friends: Carl, the llama-loving portly boy who has too many allergies to list, and Sheen, the crazy Mexican boy who's obsessed with Ultra Lord.

Jimmy has a rival: The smartest girl (but not smartest kid, that's Jimmy) in school, Cynthia "Cindy" Vortex. Cindy loves almost nothing more than to make Jimmy's life miserible. But, deep down, she secretly loves him. He, secretly, feels the same way.
