Like Castlevania S1, the art is fantastic, but the animation varies from nearly Hanna-Barbera to perfectly smooth, mostly in combat scenes.
Much of the first few eps are in Dracula's court, with his hilarious Viking vampire subject Godbrand ("I like boats! I'm a fucking Viking! We're supposed to make boats out of things!"), slutty & scheming Carmilla, the human forgemasters (necromancers, more or less) Hector (a spoiled brat with… pets…) and Isaac (harsh disciplinarian religious lunatic). And we see much more of Dracula's character and his rage at humanity. Make no mistake, I'm sympathetic to his culling, not so much to the random way it's implemented.
In contrast, Belmont, Sypha, and Alucard are pathetic. Sniping at each other, barely have any plan. They sit around and do some research, they're very reactive. The Humans are the antagonists of this season, the Vampire court are the protagonists.
The idiots (Trevor, Alucard, Godbrand) all speak like Warren Ellis, noted drunk, misanthrope, and vulgarian. The others are some of his better writing, intelligent and broken in various ways.
The plot takes quite a while to get anywhere, but for the most part it's enjoyable. FAR better start than S1 had.
Up to S2E5 now, I'll watch the rest tomorrow.
