People always talk about how reality is too boring, and that's why shows need to have spaceships bouncing around and explosion sounds and superhumans etc.
And then something like The Expanse comes out and it turns out that realism is actually really interesting. Sure, the space is unfamiliar realism, but so is serf life to most viewers. And direction is also very important.
One example I can think of is armour. In movies armour don’t seem to do anything at all. You see fully cladded soldiers getting killed by single sword blows, but people in armour are actually really hard to kill. There is a lot of story potential by treating armour like super suits, where characters get stronger with armour upgrades and elite soldiers are like Space Marines.
