Wow! That was truly amazing! As a TMNT fan since the beginning, I was practically grinning the whole time, especially towards the end.
First off, I have to give major credit to the people who animated the 80's version. It was spot on and really well done. 80's Leo's voice was a bit off though, but I grew to it later on. It was a shame they couldn't bring back the original VA's, but it's no big loss.
As for the jokes, they didn't bother me at all, and some of them had me laughing. I wish the 80's Splinter and April made more appearances, but it was great to see them once again.
Seeing still images of all the TMNT universes and the original Mirage turtles was a real treat and something I never saw coming. I was surprised they showed the anime turtles since it was never dubbed and shown here in the US.
The writers really did their homework for this special, and it was great to see Mirage heavily involved with this. Bebop and Rocksteady "defeating" the 2k3 Shredder was pure gold!
Peter Laird, Kevin Eastman, and 4kids, thank you so much for making this! My expectations were completely blown away. Thank you for 25 awesome years of the turtles, and here's to more year now that Viacom has the franchise. I hope the next series they work on will be good.
