Milly Alcock’s Supergirl joins with Eve Ridley’s Ruthye to fight an evil intergalactic human trafficker

'Supergirl' wins with its leading actress, focus on Kara storyline, fight scenes, and production/set/make-up design, but fails in its script and supporting characters.

A punk-rock Supergirl is a welcome, jagged riff on more buttoned-up superheroes, and Milly Alcock is terrific in the role.
