You don't run out of gas in space it's just bad science and a horrible problem to have for a plot device.
If that's your biggest complaint about Star Wars's abuse of space-physics, you might want to watch literally any other Star Wars movie, because there's far, far more egregious examples that you're ignoring.

It was ok. The dumbest part was the Holdo part at the end and only because it was thrown in there arbitrarily. Not to mention it makes no sense to do that yet they didn't do it during the Galactic War.
I've posted several times why the tactic wouldn't be used, except in extreme circumstances. Boiling it down to a single sentence, the Rebels wouldn't use it because every capital ship they lose is an enormous loss, whereas the Empire could weather a war of attrition easily (and they would need to be using decently-sized ships for this tactic - starfighters don't have enough mass, based on comparing the relative sizes of the Raddus and the Supremacy); and the Empire wouldn't use it because it was an enormous waste - they enjoyed military superiority, so they'd get much better results out of using their warships like actual warships rather than really big battering rams.
This is more or less the same reason why kamikaze attacks never caught on in the real world - even Japan stopped using them halfway through WW2 after they realized it left them depleted of both planes and skilled pilots.
No it was clearly just a retconn. Also the biggest issue it was just really bad writing. They did a sacrifice just to have a sacrifice. ---
