Supergirl's Low Rotten Tomatoes Score Raises Questions About James Gunn's DCU Oversight

The latest DC Universe release, Supergirl, has earned a 57% rating on Rotten Tomatoes from nearly 150 critics, considerably lower than the 83% score recorded by the earlier Superman film. The modest reception arrives as the franchise’s second installment, and industry observers note that only three Marvel Cinematic Universe movies have received similarly low scores out of more than thirty releases.

Box-office projections suggest Supergirl may generate roughly half the revenue of Superman, estimated at around $300 million, a figure below typical genre expectations. The film’s performance has sparked discussion about James Gunn’s capacity to oversee projects in which he is not directly involved as director or writer. Gunn’s previous work—including the Guardians of the Galaxy series, The Suicide Squad, Peacemaker, and the upcoming Superman sequel—has consistently achieved critic scores in the 80-90% range.

Supergirl was directed by Craig Gillespie and written by Ana Nogueira, marking Gunn’s first supervised project without his direct creative input. Critics have highlighted the disparity between the film’s reception and Gunn’s earlier successes. Some commentators reference past statements by Gunn praising other DC films, such as The Flash, which received a 63% critic rating and underperformed financially.

Analysts caution against drawing definitive conclusions from a single release, noting that the DCU has several upcoming projects, including the HBO Max series Lanterns and the horror film Clayface. The next major test for Gunn’s oversight is expected to be the Superman sequel, Man of Tomorrow, slated for release in 2028.

"I will only move forward with a project if the script is rock solid," Gunn has said in interviews, a standard he is expected to apply across the franchise.
