If we're talking anime cartoons, Fruits Basket rocks! biggrin It's not on TV or anything, but you can buy the DVD's (which are very expensive...) but totally worth it. It makes me want to start reading its Manga series.
My favorite cartoons are The Simpsons, Futurama, Family Guy, Static Shock, Justice League and Invader ZIM. Teen Titans isn't bad, and I thought I was going to enjoy the Lilo & Stitch series on Disney, as it's one of my favorite animated movies, but geez, they sucked every last bit of life out of it.
