Don't get me wrong! I've been really enjoying Crystal so far, but I have seen a lot of legitimate criticism floating around the fandom as of late and even I have a few nitpicks about the new anime.
I don't find the expressions that great, and the faces are kind of generic-looking to me. But thankfully the good voice acting has been making this less and less of a problem for me. espcially Mitsuishi Kotono <33
Also, I don't entirely hate the CGI, it definitely needs work. I do like that the transformations are less fanservicey.
