Picking up on what another thread had mentioned...I would say - currently there is no GREAT ANIMATION on TV.
There may be good stories and clever ideas and great graphics.
But as far as meaningful characters "acting" with real feelings and emotions- as livng breathing characters the answer is: nope, nada, nein- none on TV.
Not on Nick or Disney or Cartoon Network (all of which are major dissappointments).
Only in the feature, independent (some) and commerical (some) catagories does real character animation exist.
