True, the 2k3 cartoon took most of the stories from the Mirage comics and stone washed them to make them more palatable for Saturday morning cartoon viewers.
For what it's worth, at least they tried, and Raphael truly shone in that cartoon.
The first season of the 2k3 cartoon has a special place in my heart, for being full of potential and promise (and I think the animation was awesome then).
Afterwards, things sometimes dragged on for too long (Karai being conflicted) or just not as well executed as it could've been (Leo being emo and angsty).
However, having played and finished all three main TMNT games based on the 2k3 cartoon on PS2, I can't wait to see Platinum Games' output. It can't be any worse than those.
