Blackhat is not a very good movie.
But one thing notable about it is that it showed what actual bullet damage looks like during a battle. Bullets don’t spark off things with cute little flashes of light. They pass right on through. An AK-47 round can go all the way through a shipping container (as occurs in the movie). And it leaves big holes as it does so. This is very rare to show in a film.
When I was a kid we — as many North Florida rednecks do — had an abandoned car in the yard. We’d shoot at it sometimes, so I got to see pretty early exactly what a gun does to a vehicle. Only thing that really stopped the bullets was the engine block.
Small bits of sheet metal are like air to a bullet. Does nothing, really.
My favorite is on TV when there’s a shoot out and people hide behind couches! And the couches stop bullets!
It’s almost as bad as people jumping through glass windows and not being torn to shreds.
In Terminator: The Sarah Connor Chronicles, she puts Kevlar shielding over the furniture. She actually made her furniture bulletproof, so that is literally the only show where a couch stopping a bullet made any sense.
