The special efx haven’t gotten more expensive, cameras haven’t risen in price, writers don’t seem to be demanding particular high prices, netflix takes anything that you can pitch without saying the word disney.
So what in the world happened? X-files was an amazing show and watching it you are not only entertained but you care about mulder and scully. The show is genuinely a great time. Why did they stop making them like this?
The BBC did it first, in part thanks to a lack of ad breaks and shorter seasons.
Eg. the UK version of House of Cards is genuinely excellent and arguably better than the US version, even before Spacey.
Another thing is the production schedule on some of these shows. They’d be doing 12 hour days, 6 or even 7 days a week, sometimes writing shows that were going to be released within days. Far harder to create a coherent arc or plan stuff, when you have to write and direct far more episodes in a limited time frame.
