I'm currently five episodes into the first series of
Supergirl.
It's certainly impressive budget wise. Every episode is like a movie with action and effects that put many films to shame.
As for the series itself, it's pretty good. Comprising a decent set of likable characters, even if the suspicious boss (David Harewood) at the head of Supergirl military headquarters is just that - suspicious with glowing red eyes. Kind of smacks of the exact same thing in
The Flash with Harison at Star Labs. In fact the whole set up is amazingly similar to
The Flash except Melissa Benoist is ever so slightly kinky in her Supergirl outfit.
