I didn't particularly enjoy the redsky series of the classic toon but it wasn't completly crap it had some good things. Like for instance I
loved the new animation designs they had for the turtles and the way their bandanna where drawn. i liked the anger and frustration that was displayed by the turtles by being persucuted by every one else and it got really serious, some great drama there and it could hve been better if they had played that up a little more.
Don't quote me on this but i believe Leonardo comes very close to actually killing in this as well. Even sarcastic Raphael started to show a little darkness in reaction to his frustration of the turtles treatment. A few of the episodes where tolerable but seriously i enjoyed season eight beter than nine and ten.
what i didn't like was Carter, I couldn't stand him OMG
and the fact that the turtles began to super mutate. I hated, hated,
hated that. Especially when the turtles started to lose every battle they where in unless they transformed and became basically depedent on them. In other words the turtles got weaker. The cop out ending of the series!
