Season 1 is a bit childish which is probably why it only has a 6.7 rating, but season 2 and 3 is where Jimmy Neutron really shines. The character development/interactions, the witty humor, the plot are all amazing, especially for a show aimed at kids. This is definitely a show that I recommend for teens/adults. Most cartoons have 0 character development which makes them dull, but Jimmy Neutron actually develops its characters and you grow with them. There are quite a few extended episodes which are very well written and there was a lot of effort put into the creative story lines. Each season got better and better and it was a real shame that Jimmy Neutron got canceled as it was really starting to become something. The show really took off after season 1 and it really deserves a reboot from Nick because this show was a real hidden gem. Even if you've never seen the show, you will feel nostalgia as it goes over many topics that we all experienced in our adolescence.
