Okay, stuff I liked about the original series:
*The theme song. One of THE best theme songs EVER. Many of the BGMs are instantly recognizable, too
*Krang and Shredder crack me up, even when I watch the old episodes today. So many jokes went right over my head back then
*Cam Clarke as Leonardo. He made Leo have such a sexy voice
*Uncle Phil as Shredder
*Body-switching/personality modifying/typical ridiculous cartoon plots
*Girl mutants (i.e., Mona Lisa)
*Love interests for the boys (Lotus, Mona, Kala, ect.)
The new series:
*How it follows the original comic pretty closely
*The jokes are updated for today's audience
*The characters are more fully developed
*The fight scenes rock
*Great background music
*When something corny occurs, the cheesiness is pointed out and joked about
*More Casey Jones
*An actual plot
I can go on for ages about either.
