The main problem with "off-world" stories for me is their believability - or lack of it.
Hang on - I know it's
all make-believe (

) but let me explain.
For example when a planet is visited, for simplicity of story, the whole planet is treated as one "country" as it were. At most there may be conflict with another colony nearby, but rarely to we visit a planet and hear about the wide variety of people, countries, etc all over that world.
If we're going planet-hopping, let's have a more thought-through, international approach. Visit two sides of the planet, for example.
Now they've got the bigger budgets, why not?
