I also have really mied feelings on this.
I've always been a HUGE Turtle fan...
I read the comics, I watched the TV show in the 80's the live action one in the 90's (?) and the animated one that was pretty recent, ( and crappy)... I also really loved the movies... (yes all three... so sue me.)
I have a lot of memories and loyalty to this particular series in any shape or form, so I'll definitely see the movie, but I'm not sure if I'll dig the shitty graphics... art has become an important element in my regard towards a personal rating of any animated movies.
Sigh... please don't screw this one up... The Turtles had a hard enough time dealing with Vanilla Ice, travling through time, and a female turtle... ugh.
