The dismissal bell has sounded for the last time…’Class,’ the ‘Doctor Who’ spin-off show that premiered in the U.S. in April, has been canceled. BBC3 head Damian Kavanagh confirmed:

“There was nothing wrong with it. I thought [creator] Patrick [Ness] did a great job, he explored an amazing world. In honesty, it didn’t really land for us on BBC3; some shows don’t and I have to make decisions about what we’re going to do from a drama point of view.”

The show began with a story following four students at Coal Hill Academy played by Greg Austin, Sophie Hopkins, Fady Elsayed, and Vivian Oparah. The students, all coming from various social circles, are forced to work together to protect their school from alien threats.

‘Class’ premiered on BBC America on April 15. The series was an attempt to build a dark, young adult story set in the world of ‘Doctor Who’. The main setting for the show was Coal Hill Academy, which is, of course, where Clara Oswald (Jenna Coleman) taught during her time on ‘Doctor Who.’

Even a brief appearance by outgoing Doctor Peter Capaldi couldn’t help the show, which did not resonate with fans of the ‘Doctor Who’ universe.

Ness, who served as executive producer with the team behind Doctor Who, said in his Twitter feed:

“I’m not an unopinionated man, but all I’ll say re the Class news is how proud I am of that show & how lucky I am to have had the opportunity. Ah, thanks for all the love about this, you beauties. And as I’ve said, pity no season 2: Weeping Angels planet, shirtless wood-chopping…What a great experience to make it. And SUCH a great cast. And thank you for all the love for it, too! Would that things were different…”

Ness also wrote the screenplay for the movie adaptation of his book ‘A Monster Calls.’ He is now ready to bring another one of his works to the big screen; ‘Chaos Walking’ is currently filming under the direction of Doug Liman (Edge of Tomorrow) with an all-star cast including Daisy Ridley, Tom Holland, Mads Mikkelsen, Kurt Sutter, Demián Bichir, and Nick Jonas.
