When the Peacemaker character, played by John Cena, first appeared in the 2021 film "The Suicide Squad", many viewers considered this violent, self-confident disabled superhero only as a funny side character. However, James Gunn knew that this character held a completely different story within him. The resulting series became one of the boldest, most personal, and most unexpected works in the DC universe. Peacemaker is a tragicomic portrait of a man who is ready to kill anyone to ensure peace. But this definition falls short of capturing the true depth of the series. Gunn places something much darker under the superhero fairy tale: Are innate tendencies what determines who a person is, or the environment in which he was raised? How heroic is this man who wears a helmet on his face, and how much of it is a product of his own woundedness? The series chooses an extremely unconventional way to pose these questions. On one hand, there are gory, action-packed scenes and an absurd sense of humor; on the other hand, there are heartfelt, at times heart-wrenching, human moments. This balance would easily collapse in other productions; in Gunn's hands, it functions almost flawlessly. Each episode both makes the audience laugh and makes them think, while keeping them intrigued about what comes next. John Cena delivers the most mature performance of his career in this role. It is not an easy task to simultaneously carry the tension between the apparent rudeness of the character and the Decrepitude inside, his predisposition to physical comedy and the dramatic weight. The supporting cast is equally strong; Danielle Brooks especially brings a remarkable energy to the screen. The atmosphere of the series is also unique. The opening credits set to metal music, along with the popular culture references that define Gunn's style, and the tone that intertwines sadness and chaos... All of these elements elevate Peacemaker from ordinary superhero entertainment to a truly original work. After watching, you continue to think about the character; this is one of the most valuable rewards for a TV series.
