Which precisely is why it would make for a good followup movie with the right budget. Just enough that's familiar from Titanic, but with a different setting of WW1 and a different ship usage with it being a hospital ship and a different scenario for the sinking. And it apparently sank quicker than the Titanic too.
Is there enough sense of doom if the majority of people survive though?
I hadn't heard that it sank quicker. I know they stabilised things enough that they tried to head for the coast so they could beach the ship before it went down but moving at speed just sped up the water coming in
