The Mirror reports that the BBC has canceled Doctor Who spin-off Class. Officially, the network is saying no decision has been made yet. The show disappointed in the ratings in Britain, so a cancellation wouldn’t exactly come as a surprise.

Class is still set to air stateside on BBC America starting April 15th.

Set in the Doctor Who universe, Class features all-new heroes, villains and aliens. All the time travelling over the years has caused the very walls of space and time to become thin. There’s something pressing in on the other side, something waiting for its chance to kill everyone and everything, to bring us all into Shadow. Four Coal Hill School sixth formers will face their own worst fears, navigating a life of friends, parents, school work, sex, sorrow and possibly the end of existence.
