Can't actually say they're many cartoons which I enjoy of today's time, but certainly the ones of Disney, Nickelodeon, Cartoon Network of the 90s.
I really love the early Tom and Jerry, Bugs Bunny, Fliescher and the like. They are just so well drawn, the backgrounds take your breath away. The early Disney too like Fantasia, Snow White and Bambi. Now, the Simpsons, Futurama, Sponge Bob and South Park. I also loved Felix the Cat, both the original and the X rated movie. Ferb is pretty good. I love Perry the Platypus. Not sure about the CGI cartoons, they have no definition too 'shiny'.
