I kind of love Supergirl, but jeez is this show uneven. Just watch this clip, which showcases everything great about the series, followed immediately by everything terrible.
The Kryptonian storyline has somewhat ironically been Supergirl’s Kryptonite from day one, and last night’s penultimate episode proved that it’s continuing to be pretty terrible. Norm finally unleashed his plans for world domination, putting the humans under his insidious mind control, etc. etc.
(And in one hilarious scene, Superman shows up after having been offworld and immediately becomes a mindless drone. Not that they then use Superman to fight Supergirl, or do any of the other things you might do if you had Superman under your control. Nor does Supergirl ever go and check on her cousin. Everyone just leaves Superman trudging around on the street, almost like he’s reenacting that godawful storyline where he walks across America.)
