I will have to say that while I love the OS, this new one is far superior. The best part of the show is the story lines. By being closer to the original comic book, you can expect to see great episodes packed with the kind of action the OS never delivered. You can also expect to see episodes based on ones for the old comics.
The characters are also better represented. Not only are they off that whole pizza obsession thing, but they're also very hardcore(while still being humorous). Leo is still the dedicated leader, Don is still the brains, Mikey is still the lovable goof, and now, Raph is the hot-headed angry turtles that he was in the comics. But not just the turtles, April, Splinter, Casey, Leatherhead, Baxter Stockman, and of course The Shredder have also been improved and made closer to they're comics selves. And creating great new characters like Traximus, Ultimate Ninja, Draco, and Agent Bishop just adds to the greatness. Plus, we get to see characters from the old comic be introduced for the first time like Renet and Karai.
The animation has greatly improved, adding a dark tone to the series, and the music really fits the tone. And even the voice acting has improved. The only thing wrong with the series is the theme song, but that's a minor detail.
With co-creator Peter Laird working closely with the show, it has gone far beyond all the other TMNT shows and has now become the best cartoon intended for kids on t.v. today. I give the series an 11 out of 10, it's that good.
