DC and Warner Bros.’ “Supergirl” experienced a significant 74% drop in box office revenue during its second weekend in theaters. The film grossed only $9.6 million domestically, a key indicator for Hollywood performance. This dramatic decline cements the film’s struggling performance since its initial release. Industry rivals point to a concerning trend for the superhero genre. The film's performance is falling far below expectations for a major studio release. The box office results suggest audiences haven’t responded favorably to “Supergirl”, impacting its potential for long-term success. This slump places increased pressure on upcoming DC projects to deliver strong returns.
