One is the adventure story that almost seems scripted, one is a tradegy that is so common it makes my brain hurt.
I do concede that the missing sub is missing something, so I'm hoping that International law catches up and demands that all these "experimental" commercial subs also has $500 million in gold as balast . . . so it's a treasure hunt also, just to make the story perfect (because right now it's moved from an adventure story, to a horror, it needs a third act).
I don't need to know migrants are dieing, that's just a function of our world. I know why overloaded fishing boats sink, there is no mystery there, it's inherently a less "fun" (god that's terrible to say) story.
