“Supergirl” is the newest movie in the DCU, following Kara Zor-El, a hardened Kryptonian survivor as she journeys across space on a brutal revenge mission.

"Supergirl" is a big test for the DCU, but early indications are the live-action project might not go amazingly well.

Supergirl critic reviews are in, and its Rotten Tomatoes score is not what the DCU needs to see at this point in time.
