I actually like Opening MomoClo song. It just seems to fit nicely with the series in general and the voices don't bother me at all. (But I'm also a very casual MomoClo fan so that might be why).
I ended up watching this episode twice (once without NND comments and once with), I'm so satisfied with it in general. I wrote a research paper on the Sailor Moon anime series in college (dub vs sub and how it reflects cultural differences) so I've watched the original first episode dozens of times in Japanese as well as in English and it amazed me how closely it followed scene for scene, yet improved on pacing issues and with art more to my tastes and better BGM.
I'm pretty happy
I also find the complaints on Usagi's voice always very interesting. the last few times I've watched the series it's been in Japanese, so I now have more of a nostalgia for the Japanese series than the dub and I love her Japanese voice so much it just feels so perfect to me now to hear it again. I like all the voice acting I heard in general. A lot of it sounded very closely to how it was in the original.
I really hope it goes over well so they can continue to do reboots all the way up to the end. I want to see all my senshi ;_;
