I'm not at all worried about who they picked, as I'm sure they wouldn't be that left-field in picking what suits each character. I think they all sound okay. The clips did sound as it they are the tryout clips, with too much emphasis than normal.
Don's voice threw me for a loop too. He didn't have a hint of geeky nasalness like he used to before. In fact, I thought he kinda sounded like Michael J Fox (when he was younger)! I no like that....
Raph's okay, maybe a bit too deep... but as I had wondered in the movie, why does his voice sound so much like a New Yorker's, but none of the others did? If they all had a hint of the accent, it would have made more sense. (Goes back to her theory that Raph listened to the people on the streets more, while the only Turtles heard the cleaner accents from those on
TV)
Leo, on the other hand, I love what his VA has done for him! It sounds perfect to my ears: not too whiney, and not too deep. *doesn't know what is wrong with everyone else here*
Mikey's sounds like Mikey too, especially after his stint on the Fake News. That really sounded like what we're used too. Like a cross of movie
with the cartoon verison.
The other characters sound suiting too. Even Shredder's sounds better
that the other in the intro clip. (I assume he was in his robot mode then)
I'm also excited to see the whole intro with theme song on the TV this morning too! Which was well worth having to endure the tackiness of Ultraman Tiga...
