@animefeminist Overall, I'd say it's not the length that will solely impact my decision to watch an anime but it could be combined with other factors. I didn't watch Oshi no Ko in part due to the long premiere, the subject matter, and what I felt was overhype, but I'm more interested in Frieren so I'll check that out.

As for what kind of series benefit from this, I'd say ones where the initial premise changes quickly is the best choice.
