Peacemaker is part of what we love about The Boys, and then part of what we love about the Disney+ shows in the MCU—a Hard-R, hyperviolent, hypervulgar, superhero romp, set right in a well-established superhero world. While we may not see Batman or Superman, they and their pals are frequently referenced; and John Cena's titular Peacemaker was of course introduced (and used to great effect) in The Suicide Squad, which Peacemaker is directly spun off from.
Writer/Director James Gunn does great work to translate his world to a different medium and the cast is 100% game. Even outside of Gunn, other standouts include Orange is the New Black star Danielle Brooks, Jennifer Holland as the returning Harcourt, and Freddie Stroma as the totally insane Vigilante who is, well, a vigilante.
