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.
The show felt like that as well. And it would tell you it's doing it. Like using the slogan "girls get it done," and have a fight scene between the female heroes with a character saying, "wow girls really do get it done."
That season was bad and it was the last straw for me. I could stomach the cringe because i was watching it with frens but this was too much. Of course since then it only got worse and my standards have only gotten better.
