In a crushing blow to the future summer plans of people who like to stay inside and watch bad TV or read entertaining recaps of bad TV, CBS has decided to cancel beloved drama series Zoo after three seasons. The show came from author/executive producer James Patterson, and it all revolved around a series of violent animal attacks all over the world—to put it simply. This comes from The Hollywood Reporter, which explains that the show lasted as long as it did because of a lucrative deal with Netflix that made it instantly profitable for CBS in exchange for the exclusive streaming rights.
