Finally got around to watching it. While it's not my first time seeing Sailor Moon, I've only seen a couple episodes of the original, dubbed or subbed.
Usagi's VA is really, really grating. Yes, I know she's the original and that she's made quite the name for herself in other roles, but to me at least, it's blatantly obvious that she's a 40-something-year-old woman trying to sound like a teenager, and it's not working very well.
The animation style also really clashes with Usagi's character and the tone of the show so far. It may or may not be more accurate to the manga; it doesn't matter. You're showing us this willowy, graceful-looking girl (even drawing in her lipstick, which is relatively rare in anime and therefore sticks out all the more when it is done) and then making her a clumsy crybaby in a relatively lighthearted, comedic show? Maybe it'll work better as the storyline develops, but so far it's...dissonant, to say the least.
The CG in the transformation sequence didn't really bother me so much; I actually thought it looked rather good. (But then I don't have a problem with CG in general unless it's utterly terrible.) The sheer over-the-top self-indulgence of the sequence was more noticeable, but hey, I actually like transformation sequences so I'm okay with that.
I'm honestly not sure what to think of it yet, overall. It's very obvious that it's a Kid's Show, but so was the original, and the original ended up founding an entire genre that persists to this day. I'll give it a couple more episodes at least.
