Supergirl - S3 • E20 Ratings & Reviews
TV Line
Andy Swift
In a strangely appropriate episode for Memorial Day, Supergirl discovered that several of her fallen comrades... aren't quite as "fallen" as once perceived.
TV Fanatic
Stacy Glanzman
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?
Tell-Tale TV
Caitlin Wyneken
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.
Entertainment Weekly
Sara Netzley
In space, no one can hear you drop your secret identities. And wow, does Kara Danvers, aka Kara Zor-El, aka Supergirl, love it.
Den of Geek
Delia Harrington
I appreciate the attempt to incorporate children and Alex's desire for parenthood into the show.
Culturess
Amy Woolsey
Plenty of other superhero stories have emotion (at its best, Arrow is as much about trauma as violence), but rarely is it so unrestrained, so unapologetic.
Birth.Movies.Death.
Amelia Emberwing
"Dark Side of the Moon" delivered some touching and emotional interactions between Kara and her mother, but doesn't do much for the main story.
AV Club
Caroline Siede
I was actually genuinely interested in the High Council's debate about whether they had a duty to help fix Krypton's intergalactic mistakes or whether they should focus on protecting Argo City's remaining Kryptonians at all costs.
Autostraddle
Valerie Anne Liston
Supergirl shows up... just in time to get a fistful of Reign.
Syfy Wire
Alyse Wax
It was an involved subplot that ultimately had little payoff.
Lyles' Movie Files
Jeffrey Lyles
Dark Side of the Moon wasn't the disaster I was promised, but there were more than a few eyebrow raising moments.
