american gods has 10 eps and they were filming it 6 or 7 months (the production get longer than they planned). The crown has also 10 eps and they had spent half a year on the set. Even Gillian said at one comic con that now series are filmed longer than in the past and that is why more and more series do fewer eps for the season.

I can see why American Gods took 6 months for 10 episodes, I can even see why The Crown did, I guess royals costumes show take more time and the aesthetic of American Gods justifies the long-time filming, furthermore, those two series have 60 minutes long episodes, for only 42 minutes for xf. 

The more they film, the better, I wish they could film all year long, so we could have more bts, more pics, more everything, but in the end, I think they’ll wrap in 3 months or so.
