I really liked this show and had hoped for an awesome finale to top it off.
Unfortunately, this did not do it for me. The action was there, as was some of the gore you'd expect from a show in this universe, but overall, it was way too predictable. The new 'bad guys' seem to go on a very radical killing spree with no good reason IMO.
Everything kind of played out as I'd expected except for the very ending. But this was not the ending I had hoped for either and it was waaaay too rushed without any explanation for the final twist.
A lot of arcs were also not fully developed in my opinion and I feel this episode was more of a setup for the Boys season 4 than a Gen V finale. They even seem to start a plot point for Andre and his powers, but a series finale is no place for such a development I think.
Anyways, it wasn't awful and maybe I expected too much, but this was the worst episode of the season for me.
