Critics Consensus

Buoyed by the mesmerizing, terrifying transformation of Agent Liberty, "Parasite Lost" covers a lot of ground without losing sight of the season's overarching theme.

A-

The transformation is stunning, and Sam Witwer is killing it as one of the scariest CW superhero villains in a long, long time. He's glib and golden and furiously angry, and it's hypnotic to watch.

Though there are enjoyable moments sprinkled throughout Supergirl Season 4, overall, I'm just not connecting with the main storyline.There were even moments where I started zoning out.
