For those who have not seen that movie, I’ll briefly summarize my issue: the Bad Guys have some kind of super-serum/genetic enhancement that lets them superheat their bodies (or a specific part of it) to the point that they can slice though steel with their bare hands like a white-hot chainsaw through room temperature butter.
Yet they suffer no wardrobe damage; no one and nothing within mere feet (dozens of feet!) of them also suffer no heat-related injuries or damage. No fire-suppression system/sprinklers go off.
Now, when you think about most sci-fi offerings, this may seem a silly point to get hung up on. I mean, if you consider the Hulk, where does all that mass suddenly come from when Banner “Hulks Out?” Or the guy with a cybernetic arm that can lift a car one-handed, and disregards the fact that the rest of his organic body cannot support that kind of load?
Years ago, when I worked industrial scales, one of our customers was a steel recycling plant, with melt cradles just like a foundry. I know what molten metals, particularly steel, feels like (from a safe distance, natch). So when I see heat-related powers with no convection-related effects, I go, “Nope; nuh-uh, ain’t buying it.” And at that point, that movie is “broken” for me.
Ray guns/blasters/phasers? Ok. Hyper/warp/jump drives? No prob.
Really hot stuff, with no collateral heat-effects? Ain’t buying it.
So: what’s your Threshold of Disbelief?
