Ahead of the premiere of "The Boys" Season 4, showrunner Eric Kripke has announced the Amazon Prime Video series will conclude with its fifth season.

5th season will be the final season. I think this is probably a good idea. They can have a clear plan to wrap things up in a satisfying way. The Boys has been one of my favourite "modern" shows, but I felt they dropped the ball pretty hard at the end of season 3 so hopefully, having a clear plan for when the show is ending, they can tighten things up. For now, I look forward to Season 4 starting in a few days.
