On the islands of Cremona, a vigilante runs amok. Celebrated by some and hunted by others, the notorious "Killer B" takes justice into his own hands, armed with a sharp blade and superhuman abilities. Unable to apprehend this renegade, the Royal Investigation Service (RIS) calls upon the expertise of Keith Flick, a seasoned, yet eccentric detective who was relegated to the Archives Department following a personal loss. As crimes in Cremona begin to escalate, from stealthy executions of wrongdoers to sophisticated strikes on public figures, it soon becomes clear that there is more than one person responsible.

With the help of his impulsive sidekick Lily Hoshina, and unexpected aid from the elusive Killer B himself, Keith begins to unravel plots involving secret organizations, domestic terrorism, and human experiments. When the involvement of the RIS extends beyond the scope of justice, the extent of the government's corruption—as well as the trustworthiness of close allies—are thrown into question.

It’s so rare to see an anime of such high quality to take as many risks as B: The Beginning does. Sure it stumbles a bit along the way, but the final result is undeniably an ambitious and thoroughly entertaining ride worth watching.

The story is totally insane on paper but is somehow even more bewildering in action thanks to such lovingly crafted visuals by Production I.G. with a talented director at the helm. It is in one part a sci-fi police procedural similar to Psycho-Pass, but simultaneously a game of cat and mouse like Death Note. These wild ideas packed on top of each ...

Mixed Feelings
Before watching:

Damn, this show has a really good OP! Hopefully the show lives up to it. And the PV makes it seem like it'll be a nice crime thriller.

After watching:

Okay, thanks for The Perfect World, which was apparently the ED, but I want my 5 hours back. No one told me this was Botched: The Beginning.

I wanted to like this show, I really did. I want the new shows coming out on Netflix to do justice to the medium, since they'll be available to a wide global audience who aren't exposed to anime. I wouldn't say it didn't keep me engaged throughout, but overall my ...

B: The Beginning combines two separate stories within each other, one of supernatural mystery and one with a detective searching for a murderer. The fundamental problem with the show is that both stories suck ass and don’t really connect together at all. You could rather easily cut out one of these plot lines from the entire narrative and not lose that much in terms of story quality in the other. Hell, the show may be better for it. So, don’t even read the rest of this review, just write the show off based on the word of one internet stranger alone. Trust me, I’m ...
