Kim Possible is about a teenage high school girl who is a part time super hero. She spends her days in school, and the rest of the time battling her nemeses. Each of the villains is faulted in some way that is a flash back to the coyote from the roadrunner cartoons.
I started watching this cartoon when my youngest sister (she is 24) was watching it while visiting me for the summer. The first couple of episodes, you will probably be scratching your head trying to figure out why the villains are so quirky. After about a week of watching, I was grounded enough to appreciate the humor. If you like older cartoons, or cartoons like Dexter's Laboratory, Johnny Bravo, or Courage the cowardly dog, you will probably like this cartoon.
Ron Stoppable and Rufus (his naked mole rat companion) will probably be your favorite characters. Ron is a series of random disasters that seem to always be for the best.
Take the time to watch a couple episodes, if you like it, you will be addicted.
