The episode does an excellent job of pulling together various plots in a way that feels cohesive and moves the overarching story forward.

Nia Nal has been a joy to watch. Nia adds an earnestness to the series that it lost for a brief time...

I felt like I was actually watching Supergirl again, the one I've always loved.

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.

Normally, a plot about Kara doing journalism would make me nervous; as I've noted probably too many times, Supergirl's portrayal of the media plays rather fast and loose with reality.

J'onn made his first steps towards becoming an alien detective.

Frankly, I think she went too far by ending her celebratory brunch with a toast "to health, happiness and basking in the sunshine." On a TV show, that's straight-up tempting fate.

Parasite Lost" somehow has way too much going on, yet also a lot of time to fill. It's not a bad episode, per se, but it is a bit of a weird one.

Ironically, Supergirl more successfully sidelined its hero this week than last, when she was in a full-body suit and was physically on the brink of death.

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.
