This episode was a bit weak compared to the two other natural finale episodes this season but it was still enjoyable as hell and quite easily cemented itself as the best first season of a live action Superman related series and quite possibly the best first season of an Arrowverse series since perhaps the first season of Arrow a decade ago.
I was quite surprised none of our regular leads died. If I was a betting man, I would have guessed Kyle Cushing, Sam Lane or even John Henry Irons would have made the ultimate sacrifice to win the day...but they are all alive and presumably back next season.
Its a bit of symmetry that the first episode Clark lost his earth mother Martha...and in this episode he officially mourns his Kryptonian holo dad. Its a symbolic turning of a page where now Clark is pretty much on his own and he and Lois have now moved into those mentor figure roles for Jordan and Jon. I guess we may eventually see Jor-El replaced by Lara, and that might be cool, but I'm also ok with them moving away from the holo Kryptonian parents trope that has been the norm for nearly every live action version of Superman going back to the Donner film. What started out as a way to help justify Marlon Brando's paycheck and allow him to have a bigger role in the movie has stuck with the mythos for a long time.
I've never been a fan of Clark/Kal more or less taking his orders from a hologram of his dead parents and have always preferred a Superman that decided for himself to be Superman and didn't rely on being given that mission by a computer program/ghost. I wouldn't be upset if this series abandons that trope going forward altogether, but the foreshadowing several episodes back the existence of a Lara crystal seems like I probably won't get my wish. Oh well.
I am curious where things go from here. I suspect Sam's replacement at the DOD will be an antagonist of our Super family. Someone mentioned an "Amanda Waller type."...is it too much to ask for it to actually BE Waller? I know preCrisis Waller was dead...but in this new post crisis continuity it gives them an out to bring her back either with the previous actress or a recast. I'd be up to see Pam Grier brought back from Smallville to reprise the role, or someone that takes notes of Viola Davis' performance from the DCEU.
...and here comes Nat...and if Nat is alive, anyone from the other Earth could show up. Even perhaps the evil Zod possessed Superman of that Earth.
