The 2003 version of the TMNT is and will always be my favorite! It's what got me into the Turtles Franchise as a whole, and I'll always fondly enjoy the memories I had watching it every Saturday morning! Donnie has always been my favorite turtle! His voice being done by Sam Riegel has a lot to do with it, as his voice just has his gentle tone and general softness to it that fits Don to a Tee! That, and he's the spearhead for a lot of episodes, as he is the Turtle a lot of the cast turn to when they need answers to a problem, it's just a shame that he gets close to little character development unlike the other Turtles.

I could go into more rambling, but this will do for now!
Enjoy! And Happy 19th Anniversary 2003 TMNT!
