Soo... I saw TMNT a couple days ago...
My thoughts? It wasn't the definitive TMNT experience. That honor still rests with the first live-action movie... Ernie Reyes may be a mediocre martial artist, but at least he had a good role there. I digress; it was actually an entertaining, if flawed, flick.
My gripes:
A) Too Raph/Leo-centric. Mikey was only in there for cheap jokes, and Don had - PERHAPS - 10 lines in the whole movie after his first appearance, none of which were particularly critical or plot-enhancing. This isn't to say the plot with Leo and Raph was poor - it was quite good - but it wasn't quite satisfying enough.
B) "Winters" character a tad flimsy. Good concept, but... well... if you're kickstarting a series from the 80's, I think you should start with a classic villain. Even if you wanna keep Shredder dead, which apparently they won't be doing, you could bring in one of the other villains from the comic series. Hell, I bet Wingnut and Screwloose are begging to be let back out of their box!
C) Cheesy angle with the 13 monsters. I know that ties in with Gripe B, but I thought it stood well enough on its own to be Gripe C. And I'm now critiquing my own gripes, it seems.
My kudos:
A) Kickass fight sequences. The BIG fight sequence (not the last one, but the most dramatic one... I won't spoiler it, although odds are you've heard of it by now) is actually worth the price of admission. Kicked the living shite outta anything from the Star Wars prequels.
B) Some worthy humor. A lot of throwaway jokes from Mikey, but a lot of good stuff in there as well.
C) An movie you can take your kid brother to and not feel ripped off after watching... bonus points!
