The episode opens with Supergirl flying to Lena’s secret base to try to reason with her but Lena ignores her because Lena’s already got the bestest friend she could ever have in Andrea Brooks, who used to be Ms. Teschmacher but is now the AI Lena created to keep her company when she planned on beating up former best friend Supergirl. Brooks was an Easter egg turned into a plot device drug out, which is kind of a metaphor for most of “Supergirl” at this point.
For a bit it seems like it’s going to be Superman III with Katie McGrath and Brooks shooting rockets at Melissa Benoist, but no, Benoist quickly heads back to the DEO to check in with sister Chyler Leigh and start their butting heads subplot. Benoist doesn’t want to give up on McGrath, Leigh wants to nuke the entire site from orbit.
McGrath’s plan doesn’t really matter, suffice to say it’ll involve David Harewood bringing in formerly genocidal brother Phil LaMarr to help. LaMarr’s astoundingly bad. Harewood’s lost most of his goodwill too, mostly because all of his dialogue makes him sound like the writers get his deep thoughts off an online fake inspirational quote generator. There’s even a whole “do better” thing where LaMarr maybe was responsible for getting millions of Martians killed but he’s grown since then, so you obviously can forgive your (formerly) racist uncle? But there’s still a limit. Notice Dean Cain’s heinous ass has gone missing and forgotten from the show.
Anyway, there’s really nothing to the McGrath and Benoist stuff because there’s no scene between the two of them. “Supergirl” cops out before the Crisis crossover, which finally gets introduced in the last few scenes during the terrible (and long) song montage.
But then there’s the whole other subplot about millions years old alien Mitch Pileggi, who’s still chomping the hell out of the scenery, trying to eradicate humanity only to get foiled, natch, by Supergirl and friends.
Besides being incredibly silly, the Pileggi plot line is totally disconnected from the main cast except truly godawful new cast member Julie Gonzalo, who’s probably the worst actor ever on the show, which is something. Especially since they moved to Canada in season two.
Basically it’s “what if the Cylons got here earlier and just liked messing with humans as they evolve because the Cylons are board.” Or something. Doesn’t matter. It’s shit.
The possibly worst part of the ending is it resets almost everything the show’s done this season. Sure, McGrath still hates Benoist, but she gets a do-over as far as being a planetary menace. The hurt friendship storyline seems more appropriate for “Muppet Tweens” than “Supergirl,” but really bad, really cowardly writing doesn’t help things.
I think it’s finally safe not to come back after Crisis. Leigh’s obnoxious with the new girlfriend, Benoist’s got nothing to do, McGrath ought to get out of her contract, Harewood’s a random quote generator, and on and on. It’s been hard to give up on the show because when it used to hit heights, it hit them hard. But… this season’s been hopeless.
