So, last week's episode, bolstered by Bitsie and Elsass's strong performances, was really good, but this one—to me—represents the quintessence of everything that's great about the show in general. And like Flick said, it does such a knock-up job at keeping the stakes high but also believable. For instance, when the Kryptonian body snatchers came for Lois, I had the worst feeling that she was going to end up hurt or worse. Thankfully, we were spared that would-be cliffhanger of an ending this time. The Edge reveal was a definite surprise, one that I should've seen coming. I'm guessing that he's Zod or (in terms of characterization) an amalgam of Zod and other Kryptonian villains, such as the aforementioned Eradicator.
I really like how the show consistently makes a point to illustrate Superman's preoccupation with the entire world and not just those of us who reside in his own backyard so to speak. De-power tropes generally aren't my thing, but in saying so, I recognize the need for them to advance your plot for whatever particular reason. One thing that bugged me about the episode, though, was seeing that Jon had somehow managed to procure Irons' solar weapons from an RV that was actively trying to kill him. lol I suppose he just went back after Supes did his thing and ahem, disabled the defense systems. Thanks, Dad! Speaking of dads, could Jor-El have been any more wrong about his namesake grandson's capacity for developing powers? Little dude went from super hearing to freeze sneezing over the span of just two episodes! Next up better be super speed, as he'll surely be needing it to keep up with Jon and Sarah. That hookup is all but imminent now!
Most of you probably won't agree with me on this next point, but I can actually sympathize with General Lane for taking precautions against Superman in the event he should ever go rogue. In a world as crazy as Earth Prime or any of the other Arrowverse Earths for that matter, you never know what can happen. And it's not like he was downright gunning for Supes, as was the case with Snyder's Bruce in BvS. Point being, those Kryptonite weapons he'd been busy stockpiling were merely part of a contingency plan designed to mitigate a worse-case scenario. Maybe Superman should've been kept in the loop, but even this presents a problem, as he'd no doubt use the info to his advantage in a mentally impaired or mind-controlled state.
You know, it just dawned on me how rarely I comment on the show's many eye-catching action sequences, which is interesting given the subject matter. But if that's not a testament to how well the more substantive elements come across, I don't know what is!
