Spoilers Surprisingly they didn't try to subvert expectations. Butcher kills Homelander, and Hughie kills Butcher. The show was always structured for that result and I'm surprised Kripke didn't try to pull some "Game of Thrones"-esque Arya kills the Night King. It was a very fast episode with no fat at all. I stopped watching after season 3 but wanted to see how bad the ending was. It was the most straightforward episode of the entire series.
It still got in it's usual Anti-Christian shit that Kripke loves. It wasn't a bad episode but it wasn't anything special. It was very meh, and I don't think you want your finale to be meh.
I never watched the show, seemed like subversive bullshit from edgy adults trying to make kids story’s dark and gritty and real. Which attracts woke fags more than anything but butt sex.
