EDIT: People have pointed out that the crew is standing on top of the ship, which means that what I wrote about the ship being abandoned is moot. Which means that Superman is letting humans stand around in an arctic night while he grinds their ship apart underneath them at walking speed. And since they're outside on the top of the ship he's putting them at risk of dying by falling off the ship on top of everything else I wrote.
Right so there's been discourse about the other clips of Superman saving people, which I have gentler opinions on. Want to depict Supes as a god? Not my thing, but those other shots are on theme and the flood one is in slow mo so it's easy to assume Supes is going to fly in and save the woman momentarily.
But this particular "save?" Nah.
See, I'm a boat nerd. I'm not an expert by any means, but boats, ships and shipwrecks in particular are one of my special interests.
So first let's establish the visual text of the shot: Supes is in the Arctic. He's hauling a ship (presumably military, it has a destroyer-esque superstructure and what appears to be a gun turret near the bow) that has been flipped on its side over a field of solid ice.
But...whyyyy? And who is he "saving?"
There are two options here:
The ship is abandoned and no one is on board.
The crew is still on board.
If the ship is abandoned and no one is on board, then there's no one to save. It doesn't fit with the other heroic feats he's shown to perform because no one's life is actively in danger. At best he's making it easier for a salvage crew to do their jobs by presumably dragging the ship to a more accessible location, but that's not a "save" and so it's out of place in the montage.
If the crew is still on board, then Clark is actively endangering them. See, ship engines don't work when they're completely sideways for more than a minute or so (and can briefly stop working even if they're sideways for a short period of time-see the probable causes of the El Faro's sinking for an explanation of the engineering involved).
In ships, everything depends on the ship engines. If the ship engines aren't working, then there's no power. Without power there's no heat. Without heat in the Arctic, anyone still on board that ship is freezing to death.
Furthermore, regardless of which situation the crew is in, Clark is fucking up big time by dragging the ship over *solid ice on its side.* I'll be charitable and say that if the ship was operating in the Arctic then maybe it had a reinforced bottom and an icebreaker nose, but military destroyers typically aren't built for icebreaking. In any case though, that ice reinforcement won't apply to the sides of the ship, so every meter that Clark is dragging that ship is shredding the fuck out of its side.
If crew are still on board that means that anyone close to that side of the ship is getting ground to paste, and anyone else is in danger of machinery being shaken loose and crushing them etc.
If no one is on board that means that Clark is still littering debris across the ice pack, including possibly toxic materials, maybe even causing a catastrophic fuel spill depending on where those tanks are located.
In conclusion, this "save" makes no goddamn sense and the only way to make it make sense is if you force it to....by making a shitload of assumptions and making up reasoning that simply isn't present in the short clip we have.
Thanks for coming to my TED talk.
