Bubbleblabber’s Definitive Top Ten Adult Animation Films of 2017
9) “Black Butler: Book of the Atlantic” (English Dub)

While it’s set in the same universe as the Black Butler anime, Book of the Atlantic is largely standalone. Benefiting from an original story, masterful balance of comedy and horror, as well as superb voice acting, Black Butler: Book of the Atlantic is a fresh entry in the Black Butler saga.
"There are also other characters that come and go (also owned by the Warner Bros. Discovery conglomerate media company)."
Huh. Is that just referring to other characters from the show itself, or is this implying that the new season is going to have cameos from other WBD IPs
