Oh, and a rat who happens to know ninjutsu because his owner was a ninja master and the rat copied his master's katas (cos ya know, imitating forms alone will teach you mastery in a martial art :rolleyes:). W h a t ? ? Mind you, the 80s cartoon's Splinter origin where he was the ninja master who had his genes crossed with a sewer rat makes more sense insofar as why he knows ninjutsu and can teach it (the biological side on the other hand is just as ridiculous, if not even more so (-_-)).
If you look at it from the POV of someone who knows nothing about ninja turtles... it's a lot to swallow. It might work for a comic book, kid's cartoon and kid's movies, but if you want to "mature" it and expand it for a wider audience, then it might need to be tweaked. Aliens and mythological creatures is a more convenient/plausible excuse because they can be almost anything and you don't need to create an excuse of why they look like that. Why are they giant humanoid animals? Cos they're aliens.
But the problem of making them aliens creates a new set of issues.
1/ Are they still mutants? If everyone from their planet looks like humanoid animals, then isn't that just normal for them? What's that? They're lactose intolerant?? Okay, they're mutants then. :p
2/ The concept of being teenagers is a rather humancentric concept, particularly based on a base 10 counting system (because humans have 10 fingers - the 6 fingered Sontarans in Doctor Who use a 6-base counting system; so it stands to reason that 6 fingered alien turtles would be more like to use a 6-base numeric system wouldn't it?) Teenagers for humans represent the transition from juveniles to adulthood, whereas marine turtles can take decades before reaching physical maturity (which isn't too surprising considering that many species can live for over 100 years).
3/ How are they ninjas? Don't tell me that their planet just happens to have a martial art identical to Ninjutsu and they just happen to call their practitioners ninjas. Oh, and they happen to wield Japanese peasant weapons. Unless: (a) they learn ninjutsu after arriving on Earth, or (b) a human just refers to them as ninjas because that's what it looks like to them (kinda like how "Superman" was a name given to Kal-El by Lois Lane - it wasn't originally his idea). But then... what's with the bandana-masks?? I've never quite understood why the ninja turtles hide their faces. But I think the cartoon explained it as Splinter^the audience being able to tell them apart easier. :p (although originally they all wore red bandanas)
