Pretty much all modern TV series nowadays. You can’t make a proper TV series when your actors/actresses and the rest of the crew have such long breaks. At a certain point, you just end up losing critical actors or writers or other members of staff.
The Expanse just kept going until the end, and SyFylis cancelled then, and then when Amazon cancelled them for good. Five and a half seasons in seven years, and that’s even with the cancellations and COVID.
It was only 6 episodes for the last season. I truly believe that they were trying to save as much money as possible for their LotR series, which is a shame because that series didn’t fair so well, especially with the billion or so dollars they spent on it.
