I think the Holdo manuever was brilliant. It doesn't have any real foreshadowing, thus being a complete surprise to everyone involved. It works as a movie idea because Holdo is set up as an antagonist so the main characters have no way of learning about it, and it's part of that twist: not only was she right all along, she also had an idea that saved them all, which adds to the drama of her sacrifice. It wouldn't have worked if it was an established technique and it won't work again, because it's a game-changer. There will be similar technologies deployed and countermeasures deployed, but as a reliable strategy, no.
"Sir, permission requested to do a Holdo manuever."
"You mean to take a capital ship, which might I add is currently staffed by a thousand people and would need evacuating, and ram it into theirs, hoping they are arrogant and distracted enough to not simply shoot you out of the sky."
"Yes sir."
"You are demoted."
or
"Sir, sensors show that they are evacuating their capital ship, turning it around and powering up their hyperdrives. Do we continue focusing fire on the escape shuttles?"
"Hell no, target the capital ship and raise forward shields in case of shrapnel, then carry on firing on the shuttles once the capital ship is disposed of."
It's like the crane kick in Karate Kid. It's a stupid fucking move, it just caught Johnny by surprise because he had never seen it. It was specifically countered in II and wasn't a win button after all.
