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.”
Team Flash wraps up season four with “We Are The Flash.” As is often the case with season finales, there will be spoilers here, so don’t read this if you haven’t seen it or care about spoilers. Warning delivered.
I’d argue “The Fanatical” could apply to several things on Supergirl of late, so it’s a good episode title.
The CW’s Arrow ends its sixth season with a “Life Sentence.” Since this is a season finale that aired a few weeks ago as I write this, there will be spoilers.
