Ummm, can I ask why?
The original TMNT animated series was one of my favorite cartoons when I was a kid and I still have a strong attachment to it, regardless of it's quality. It was a major part of my childhood. I couldn't care less about the newer series. I gave it a shot, it wasn't for me and I moved on. Maybe my feelings toward the original series is clouded with nostalgia but who are you to tell me that it's a bad thing?
Don't make statements like that if you can't elaborate. Not everyone at TZ is young enough to call the 2003 series their TMNT.
