Director Craig Gillespie’s Supergirl, starring Milly Alcock as the Maid of Might, is not taking off at the global box office. The film grossed about $37.1 million domestically in its opening weekend. It has made about $74 million globally so far. The film is underperforming financially and critically; Deadline recently reported that Supergirl could lose WB $125 million. There are numerous reasons why this film was a failure, but the most prominent is that the comic book stories of Supergirl are not that popular.
