Why are there no serious space sci fi shows on television?

[N7Soldier11]

I enjoyed all three seasons of The Expanse and I intent to watch it on Amazon but I find it sad that there is no big space opera on TV now.

What happened? Have we lost interest in space? Have we become too cynical for the future?

I have heard people complain that The Expanse is too slow and lacks a "sense of wonder".

If space opera is to return to TV does it need ridiculous things like space fighters and humanoid aliens?

Some random reasons I can think of:

1) We had a big hype for space when the first moon landing was, greatly broadening the audience at that time for anything space-related

2) the TV is more and more a tool for an older demographic, so you are more likely to find sci-fi in other mediums (games, streaming services and such)

3) (a bit similar to 1) the novelty of space-travel has faded a bit, so other topics of science-fiction are currently more popular
