I grew up watching this and I have to say it still holds up well. The stories are creative, it's usually an invention Jimmy creates that later causes more problems than it initially solves the animation's pretty good given the budget and the main characters have well-defined personalities which makes them entertaining to watch especially when they show signs of development in the later seasons. Basically the premise is about the title character (Debi Derryberry) who navigates life with his friends and inventions. While trying to make things better with his inventions he ends up causing even more trouble that he has to fix.
Helping him are his friends the neurotic Carl Wheezer (Rob Paulson) and the hyperactive Sheen (Jeffrey Garcia). He also his to deal with his rival from school Cindy Vortex (Candi Milo) who sometimes sabotages his inventions. As the series progresses he also has to deal with various antagonists such as aliens from different planets who either want to enslave earth or get revenge on Jimmy for foiling their schemes. I don't have much else to say other than if you like wacky adventures and witty jokes than you'll like this.
