I just had that exact experience. Checked it out for the first time a few days ago, just finished that last episode and came here to watch this after reading an interview where the showrunner mentions this video being on KZfaq. I was impatiently awaiting The Boys Season 4, and saw a video on KZfaq called something like "Antony Starr was Homelander before he was Homelander" and it was scenes from this show. I checked the show out and was hooked pretty early on... a bit too much on the sexual side in that first Season, but I liked the story they were trying to tell and it only got better from there. This show did something I think was interesting. While the story was important, most of the time the Storyline is A and the Character are B. Both are important, but Storyline comes first. With Banshee however, it felt like Characters were A and Storyline was B. I think this actually worked in it's favor making all of the Characters QUITE memorable. I normally forget many of the characters names, but not with this show. Every single one of them felt different and unique and flawed in their own way and that's what made them all great and really memorable. These are the most realistic Characters I think i've ever seen in a show.

Come on, this show deserves a closure in one's heart, you won't regret it man
