It was Amazon’s biggest show of all time and every single metric that was a big success for them. The only people claiming it wasn’t are people who are just arbitrarily saying “it cost a lot so I think it should do more” without any real knowledge of the economics behind it.

Aka it’s a vague claim that has nothing to back it up by people in a sub that didn’t like the show before it was released

Also Dahmer is on the biggest streaming platform in the world and it outdid many more expensive shows, that’s more about how much of an out of nowhere hit and a testament to its success.
