I’ll go ahead and find flaws in that video, just for the discussion.

On the subject of the first act structure not making sense for Lex to pull the Hammer out when Superman is defeated even though his goal is to kill Superman, it does make sense.

First, the fight as the Hammer was clearly a live test, to see if it would work.

Second, the plan to actually kill Superman relied on the Engineer and her nanites suffocating him, because Lex has already determined that just beating Superman may not be enough - or at least, he’s not sure of it yet.

Third, if he did try to beat him to death even with the risk that the Sun would be enough to keep him alive, it would surely require ditching the Hammer suit and letting Ultraman loose with better movements and all. That would put his role in it at risk, since the actual kill attempt that we eventually saw had no witness. Until he said fuck it and tried to rip the planet apart, anyway.

Fourth, with the later comment on the pocket universe scene a bit further in the video - it looks like he doesn’t even know exactly how much it really can hurt Superman. It certainly would be the perfect time to bring the Engineer and Ultraman, but at this point he thinks he just won and it’s only a matter of time and everything is coming together. So he plays along with the government, and then he’ll savor the kill. Which is pretty typical and not that weird for a supervillain.

After that, suggesting the reorganization of scenes and that the argument between Lois and Clark be interrupted by the fight would show the balancing act in Clark’s life, I think is just the exact same thing we see in any other “superhero with a secret identity” movie.

The part where he points out nothing is done to the baby, and maybe it means Lex wouldn’t actually hurt a baby - it’s the other guy who doesn’t do shit, the guy holding the baby. Looks to me like it’s just that guy’s fault for not understanding what’s going on when a bright Sun is being created in front of him and blinding him. In fact, it looks like he’s not even holding a gun or anything - not that I think Lex didn’t give him any (I do assume he has one somewhere), but that the guy really thought it would be smooth sailing and wasn’t expecting to have to do his job, especially the way he was mock playing with the baby just to be a dick to the dad. Sure, it’s a writing choice and it’s disputable, but it’s not really a plot hole.

As for the whole flawed villain, flawed subplots - Lex’s character literally carried 3/4th of the movie, and it work as long as you’re not trying to push the whole movie into a copy of all other Superman movies. Likewise, the stuff about Jimmy and explicitly saying “maybe that part of the character is the joke, but I prefer (the opposite)” is just him disagreeing with the choice and barely accepting that, yes, that is indeed the joke, and it is funny enough, it doesn’t have to be explained with Jimmy’s full history. And the girl turns out to not be dimwitted - like Lois says, she’s a genius, she just has insane attachment issues (“my mom ? you only met her once !”). That’s not dimwitted. She did know exactly what she was doing, and planned it for her safety. She’s just really nuts about her love life.

etc. I think the video is trying to nitpick a little too much. It’s okay to feel the structure is off and all, and try to discuss it, but it’s a bit much to claim that those are actual flaws, and not just stuff you’re not very fond of. It’s just a choice, and it’s more about presentation.

The fact that they fight twice in a row with the same resolution is a little odd and repetitive at a glance, but I imagine it was done to have a more surprising opening for Superman who you’d normally assume would never lose a fight - it’s even part of the text crawl, “3 seconds ago, he lost a fight for the first time in his life”. And then you see it happen again with your own eyes. With the way this Superman is presented, this is clearly meant to instantly make him more relatable and not the usual invulnerable plot device “it’s literally in the job’s definition that he’s stronger than everyone”. And unlike a typical superhero movie, that’s not the mid-season shock defeat that will lead to the superpowered upgrade. It’s not made to be put there.

I would think that the fixes he proposes are getting further away from the Superman that James Gunn wanted to give. Like Superman’s entire reason for surrendering is finding where they put Krypto, just because he’s that carefree. It just removes what makes this take different from the usual Superman movie - or any other superhero movie. And I think this actually takes away from the representation that Clark does, in fact, have a normal life, is relatable and actually very human, and that it doesn’t need to be interrupted by a superfight to show drama and personal conflict. That part is even subverted later when the giant space cellular thingy is fighting Green Lantern outside at night, and Superman just says “whatever, he can handle it, it’ll be fine” and instead takes his sweet time to tell Lois “I love you”. I think that this blends both aspects of his life a bit more, with Superman still having a bit of Clark not immediately responding to every problem, and Clark still having a bit of Superman when he gives Lois the interview and gets upset at people dying - he’s speaking as Superman but you’re watching him in Clark clothes. And that’s also a choice, not a flaw.

It just looks like the guy disagreed with Gunn’s choices to make this Superman different and more relatable as a human, instead of the usual invulnerable wall as soon as he puts up his costume. That deal is sealed when Superman doesn’t save Jaranpur (spelling ?), the upgrade does. And yeah, the outbursts were super weird as early as the initial trailer, it’s super off to watch Superman lose his cool like that and shout - but that also ties back with the speech of being human and making mistakes. I expect the next movies to start smoothing him over a bit, getting more experience and more relaxed with his emotions, full All Star Superman. We already know that’s the goal.
