I have said that for sure. The problem with most D+ shows are that they don't give enough time for the story they're telling and have to rush the ending. I do think Acolyte suffered from that as well in a way. But longer episodes wouldn't have helped. They need a better written and formatted show.
I agree don't spend 200mil, I've been critical of Disney budgets for a while now as you know. I don't think the traditional format is the answer though. A 10 to 12 episode season averaging 45min an episode would be good. The advantage of streaming is you don't have to stick to traditional ways. If you need an hour for an episode, use it. If 30min is enough, great. If it works out to 11 episodes, that's fine too. But it all starts with a compelling story and show. And the acolyte wasn't.
I think it is secondary, that was my point. If the show was really good, like my Andor example, it will most likely get another season at least. Mando went bonkers, baby yoda became a phenomenon. It was getting multiple seasons and now was rewarded with a film. It had good ratings, but the merch took it to a whole different level. The Acolyte fell so short of that, it just couldn't be justified. If by some chance it managed to do well with t-shirts, action figures, collectables... It might have justified a second season. But there was zero engagement with the show.
