Star Wars

If you like "realistic" Sci-fi, I highly recommend "The Expanse".

Until what could have been the end of the series, there was no way to travel faster than light or any kind of "jumping", just interplanetary travel in our solar system.

The characters have believable day to day jobs, and the political structure and technological advances are incredibly believable.
(earth still has a high unemployment rate and the "UN Secretary General" is the de facto ruler of earth, while a former colony on mars has just won a war of independence from earth and has newer and better tech and ships but is dependent on ice mining from asteroids for water, done primarily by "The Belters", born in space and recently and tensely aligned into the "Outer Planet Alliance".
(there's a lot of turn of the last century Irish immigrant influence in Belter culture, and I'm told "in the book" Belters all have longer limbs because of being born and living in zero G their entire life)

So far the "new season" has been a slight let down as it seems to be entirely focused one one planet and what used to be a good gag of having the Secretary General drop the F bomb has become so common it could be a drinking game.

The writers of this series seem to have anticipated being cancelled as every season finale could actually be the series finale, even though there is a very involved long running plot. Genius.
