ZOO is a global thriller about a wave of violent animal attacks against humans sweeping the planet. James Wolk will play Jackson Oz, a young, renegade American zoologist who spends his days running safaris in the wilds of Africa when he begins noticing the strange behavior of the animals. As the assaults become more cunning, coordinated and ferocious, he is thrust into the race to unlock the mystery of the pandemic before there’s no place left for people to hide.
It is being reported that CBS has cancelled its summer thriller Zoo. The move comes one month after the conclusion of its third season, but was somewhat expected after its ratings performance during its most recent run.
The show premiered in 2015 with a successful debut that saw it rank as the summer's most-watched scripted series. While viewership tapered off in Season 2, it wasn't until this season that ratings fell to levels that put it in danger of not continuing. Many viewers reported tuning out this time around after the story took a jump into the future with uneven storytelling and off-putting hybrid animals.
Zoo's cancellation bares similarities to that of Under the Dome, in that both are CBS shows that broke out with successful summer outings and ended up airing for three seasons and exactly 39 episodes.
