This is a season finale. So there will likely be spoilers in this review. Bear that in mind before reading.
I’ve been saying this season of Supergirl wasn’t that good. In “Make It Reign,” I only had to wait for the first scene to wonder who was writing this nonsense.
Last episode ended on a serious cliffhanger/start of a fight, and “Not Kansas” picks up in exactly that spot. Supergirl and Mon-El, just back from their unexpected Argo City vacation, arrive just in time for a major fight with Reign in Lena’s lab.
Taking a break from the urgency of the World Killers, even if this mission is related, Supergirl works towards her season finale with “Dark Side of the Moon.”
I’d argue “The Fanatical” could apply to several things on Supergirl of late, so it’s a good episode title.
Supergirl starts rushing towards her season finale as the cast takes “Shelter From The Storm.”
The fight with the World Killers is building to something truly impressive as we see in “Trinity.” After so many secrets were revealed last episode, Lena Luthor is being questioned by the DEO, especially Supergirl, Alex, and J’Onn.
