What a treat! I can't believe it's been over ten years since the last time UY was animated.
Episode 1:
Great to see bits of Stan's art, and the fact that he wrote it. As per tradition, Usagi must first battle the turtles until they all realize they're good guys. Gotta do it.

I like how Usagi just touches his scar as his flashback ends, without there being any other explanation about it. There didn't need to be. Nice brevity of storytelling!
Design: overall I like this interpretation of Usagi, except for the fact that they give him a right eyebrow, and in the precise symmetric place opposite his scar, letting that substitute for his left eyebrow. It confuses the fact that it is a scar, and not just a differently colored eyebrow. And besides, Stan almost never draws a right eyebrow. Sometimes a line to denote certain expressions, but only when necessary. Just a little design aberration I wasn't thrilled with.
I did not enjoy the bratty little child character because I do not enjoy bratty little children. I know storywise he's supposed to be, but it detracted all the same.
But overall it was a good introduction to the UY world for newcomers and a joy for those of us familiar.
Episode 2:
What happened to the horses? They're either stuck in the tree or fell to their deaths offscreen.

Sadly, I find this episode to be filler. There isn't much character or story progression, it's just stuff that happens. Nice to see yōkai, though.
Episode 3:
Now this is more like it. A nice conclusion, with more usage of Stan art as Usagi rallies. (RRYYYAAAAAAA!) And the anticipated beginnings of de-bratification of the boy.
Impressions as a TV cartoon overall:
This is the first time I'd seen this iteration of TMNT. REALLY cool opening title sequence, even though it's a blatant ripoff of Cowboy Bebop. I like the opening and closing music as well.
I'm happy for Seth Green to have a fun gig like this, but it's hard for me to suspend disbelief when Leonardo is talking. I just hear Seth Green. I see someone else did it at first.
Tone: I exceed the age of target audience by quite a bit. But it's more juvenile than I'd have hoped. Just a hair too much tomfoolery and pointless roughhousing and the like. But I'd probably feel the same way if I was around four real human teenage boys, much less mutant ones. I don't recall there being quite so much of this in the previous incarnations, but it's been a long time since I've seen them so there might have been. Come to think of it, the original had a lot of pizza-throwing slapstick and such. Didn't like that then, either.
