The Peacemaker Season 2 finale, titled "Full Nelson," received mixed reviews and is considered by many fans and critics as the weakest episode of the season. While it delivered emotional payoff and character growth, it fell short on action sequences and left some storylines unresolved, which disappointed viewers expecting a more traditional superhero finale. The episode notably sets up future plot threads for the DC Universe, particularly tying into the upcoming "Man of Tomorrow" movie, and introduces the concept of "Salvation," a prison planet for metahumans. Rick Flag's villainous turn in the finale was seen as cartoonish and contradictory to his previous portrayals, which upset some fans and critics. The new peacekeeping agency "Checkmate" was established, signaling a significant development for the show's universe. The finale ends on a cliffhanger with Peacemaker being imprisoned on Salvation, which leaves his fate uncertain. Despite its shortcomings, the episode featured strong emotional moments, including key relationship developments for the lead character Chris Smith (Peacemaker) and resonant scenes with supporting characters. However, with no current plans for a Season 3, some fans are left with lingering questions about unresolved plot points.
