But, I agree with the above poster who said that the first Turtles movie is underrated when it comes to comic book adaptations, it's really quite strong in that regard in tone and certainly in look. There's a couple "lip syncing" issues in the movie but, damn, the animatronic heads and the costumes are just damn-near flawless. I mean they just look great. The only maybe minor quibble I have is how bendy and flexible their ventral shell is. But, damn, they look great.
Now that we're having this talk, I've started to realize what may be a major reason why the first movie is so superior to II and III: having a strong theme in the first place.
We're all aware of the theme of fathers in the first movie. EVERYONE in the movie has a role in that theme -- the Turtles/Splinter, April/dad's shop, Danny/April's boss, even Sam Rockwell verbally sparring with Casey Jones about Shredder as father. But what's really surprising to me was, by comparison, how much the next two movies just don't even try to have a central theme to guide the movie and the characters and tie everything together, so much so that they just become a set of action pieces connected by flimsy plot. Sure, there's lip service about being brothers, but the first movie constantly reinforces the theme without being so blatant about it.
I do find it humorous they tried to "tone down the violence" by having the turtles use their weapons less but in the big fight with the robbers at the end we see Donatello twirl a yo-you around his head to knock some of the robbers out. Which, correct me if I'm wrong, is just as bad if not worse as him hitting them with a stick.
I hate to nitpick (wait, no I don't! I'm on a Star Trek message board) but it's Michelangelo who uses the yo-yo.
And Michelangelo even substitutes his 'chuks with sausages. Ugh.
Looks like the script was retooled after all.
And that, I'm at least glad about, for a multitude of reasons, as far as it concerns the Shredder.
