I was reading up on this decision, and apparently the show runner states they did this to foster discussion in the show:
“This was from the producers. We wanted this. It was a creative choice.” Kripke continued, “So they may like it or not like it, but they have to at least respect that the people who are making the show wanted it to be released this way because we wanted to have time to sort of slow down a little bit and have conversations about everything.”
He then goes on to complain about getting review bombed:
“We’re fine, and it’ll be fine, but i’s not fun to see bad reviews on a thing people actually love. Like, that doesn’t make the people who make the show feel good. I’ll say that.”
So they made a bad decision that affected over 50% of the viewership of the show but are upset that people used the only tool they had to tell them loud and clear their decision was not appreciated. The hubris here is amazing.
