Critic reviews for Dark Side of the Moon

In a strangely appropriate episode for Memorial Day, Supergirl discovered that several of her fallen comrades... aren't quite as "fallen" as once perceived.

Nothing is ever easy, is it? All Kara needed to do was get some of this black rock, but she discovered that the very thing she needed to save Sam, was also the very thing keeping her mother and fellow Kryptonians alive. Wait, what?

A huge revelation changes everything Kara knows.

A lot of these plots could have been fun given enough room, but all slammed together into a hot mess they left me wanting to punch the brakes.

In space, no one can hear you drop your secret identities. And wow, does Kara Danvers, aka Kara Zor-El, aka Supergirl, love it.

I appreciate the attempt to incorporate children and Alex's desire for parenthood into the show.
