I'm lucky in that I go to a shool that has a film and anamation departments 3-D & 2-D. So they show films in the lobby everyday including the weekend.
Fantasia 2000
Ice Age
Osmosis Jones
the one about the boy and the giant robot set in the 1950's
Monsters Inc.
Shrek
and a few others I can't think of at the moment.
I haven't seen the trailer for the new movie but will keep a look out for it.
The current cartoons I love to wtach are:
South Park
Daria (it's over but the re-runs are showing on The N.)
PowerPuff Girls
Justice League
SpongeBob Square pants
re-runs of Ren And Stimpy
re-runs of Pinky and the Brain
re-runs of Anamainiacs
Edited to add:
Wallace and Gromit
