I never watched the new series, but those Turtles seem a bit bland. However, the running gag of the 80's/90's Turtles being nearly ineffectual goofballs is pretty great, and it's a lot of fun to see the juxtaposition of the old with the new just for the comedic opportunities. The introduction to "Turtle Prime" is also hilariously awesome.

All points are given from a heart of nostalgia... I freakin' love the TMNT!

I want to see a live action version of the classic noir turtles. ASAP. (Bring in Elias as Casey and you have a sure-fire hit, I'm telling you.)

Surprisingly enjoyable even though I never saw the new series. The jokes were good and the interplay of the two groups was done well, mocking both the old and the new show with some funny running gags. If you liked the show in the '80s (who didn't?) you can give it a try, it is nice to see all the characters again.

It was a silly romp through Turtles past.

Meta-bunga, dude.

This work had its flaws, to be sure, but it was enjoyable. I can see myself watching it again.

Mixing different generations of turtles is a great idea. But it hurts to see "my" turtles ridiculed in this way. They were definitely not this goofy and irritating. The same goes for the classic Shredder and Krang. The noir turtles are awesome however.

Pretty good movie and great to see the old turtles back in action.

They really couldn't find Uncle Phil to do Shredder's voice? Was he that busy? (Or any of the original voice actors, for that matter.)
