The season finale of Superman & Lois, titled "What Kills You Only Makes You Stronger," is a study in contrasts, much like the season itself. It's an episode that starts with the promise of hope and happiness, only to be overshadowed by the looming threat of Lex Luthor and the emergence of Doomsday. The finale is a rollercoaster of emotions, with moments of triumph and frustration that encapsulate the series' third season.

The episode begins on a high note, with the residents of Smallville moving forward with their lives after a year of challenges. Lois Lane is embracing her newfound health, coming to terms with the physical changes and the emotional journey that her battle with cancer has wrought. The scene where she and Clark Kent reconnect is tender and genuine, a testament to the strength of their relationship.
The Kent boys, Jonathan and Jordan, are also looking towards the future, planning a community event to watch a meteor shower. This moment of brotherly unity is a heartwarming contrast to their earlier conflicts, showcasing their growth and the bond they share.
However, the happiness is short-lived as the specter of Lex Luthor casts a dark cloud over the proceedings. Luthor's quest for vengeance against Superman and Lois is a driving force of the episode, and his manipulation of Bizarro into becoming Doomsday is a chilling display of his cunning and ruthlessness.
The transformation of Bizarro into Doomsday is a highlight of the finale. The creature's rampage, fueled by Luthor's machinations, is a thrilling sequence that sees Superman engage in an epic battle that spans from Smallville to Metropolis and even into space. The fight is a visual spectacle, showcasing Superman's power and his unwavering commitment to protecting the innocent.
The finale also explores the personal struggles of the characters, with John Henry facing a difficult decision between a promising job offer and his budding relationship with Lana. Sam's budding romance is cut short by a betrayal that ties him to Luthor's schemes, adding another layer to the villain's web of deceit.
The treatment of Jordan's character in the finale is a mixed bag. His frustration with being restricted from using his powers while being asked to transport the family to Italy is a valid point, but the way it's handled feels inconsistent with Superman's teachings. The forced apology to Sarah also rings hollow, as it doesn't acknowledge her own mistreatment of him.
The finale's climax, with Superman and Doomsday's battle on the Moon, is a visually stunning and emotionally charged sequence. It's a fitting end to the season, leaving the audience on the edge of their seats as they await the outcome of this epic confrontation.
Despite some missteps, "What Kills You Only Makes You Stronger" is a largely satisfying conclusion to the season. It sets the stage for a new chapter in the series, with Lex Luthor's machinations and the threat of Doomsday promising a thrilling season 4.
The finale is a fitting end to a season that has had its ups and downs, but ultimately delivers on the promise of a superhero show that balances personal drama with larger-than-life action. It's an episode that leaves the audience eager for more, ready to see how the story of Superman & Lois will continue to unfold.
