I couldn't watch it on Hulu cause I don't like in America (Fuck you, Hulu) but I did watch it on NicoNico. It's good. Different enough that I can say it's definitely a new anime, but still the same. Nice to see Kotono reprise her role as Usagi, although I'm curious to hear the new voices for the inner senshi. (Although I'm sure Koshimizu will do a good job, I've heard her for other characters and it's a fitting voice for Jupiter)
I'm definitely with you on the F-you to Hulu. I use Crunchyroll for my anime. I was glad Kotono was Usagi again as well. The first few minutes of the episode was a giant smack of nostalgia for me. My favourite of the inner senshi was always Rei, so I'm eager to see her in the next episode. I hope her actress does a good job.
Rina Sato? Hang on, lemme check her name... From the list, I haven't heard her very often, I think only once as Negi Springfield in Negima, but that memory is hazy. I'm sure she's good though. Ami's new voice actress may not be Hisakawa, but she still does a pretty good job at it. Although I have begun to notice some... problems with the new anime... *sigh*
