Wasn't it the opposite? He was initially running Discovery, then both shows, and then left/got fired from Discovery and was only working on American Gods?
Yes! Dear lord I'm misremembering more and more these days. I was stoked he came on board to reignite the Trek franchise, *then* he departed for American Gods.
After that there was another show with 'Daisies' in the title (I think), which IIRC he also departed. I never watched it.
Budgetary issues seemed to a common thread in his productions. Season 1 of AG was fairly expensive, and he wanted more for S2. Gillian Anderson chose not to continue on in her role after his departure.
Such a frustrating show. I wasn't a big fan of S2, but felt they'd started to right the ship in S3. Then cancelled.
