universe is missing the point of fiction media!" then they’ll turn around and mock visionary shows like NCIS for scenes in which the detectives enhance the resolution of an image. Oh, computers can’t just do that? Who cares! Lock in! The point is not that the story makes internal sense, it’s what the story communicates!
Where do you stand on “There was room for both Jack and Rose on that door. Jack didn’t need to freeze to death in the Atlantic” discourse?
While set in a historical setting, Titanic is a melodrama, Jack has to die at the end. Plus I don’t think misleading people on door buoyancy is going to have much negative affect on society, unless you and your partner end up in a freezing body of water with a door as your only flotation device.
I’d say a bigger inaccuracy in Titanic that is actually bad and worth criticizing is that one crewman who shot a dude and then killed himself. He was based on an actual crew member of the ship but in reality neither shot anyone or killed himself, his family was pissed about that.
