When Truculent got blown up by c4 it shouldn’t have torn him to shreds. The explosion should have destroyed all his insides and momentarily expanded his invulnerable skin like a balloon, which should have contracted to a boneless sack of goo. At least that’s how I would have done it. Maybe they thought of that and decided cleaning up the mess had more comedic effect.
That’s the least egregious example tbh. Every shoe is seemingly invulnerable until the plot needs them to not be, at which time they’re easier to kill than a human being.
