Fredrika was the worst imo, but I know that others disagree, and I know the Beelzebubs are the single most complained about monster. Looks like Black Alice might have them both beat imo. And Chrome is back, so yeah. I don't have any Japanese friends I've just been keeping my ear to the ground and lurking sites like gelbooru. I've seen a lot of the cgs for some of the bigger moments. The Granberia fan in me was not displeased. I haven't heard anything about a 4 though.
And yeah, I found him a little while ago, although I saw links to his videos a lot before.
