Hate leads to Suffering.
While his ideas are big and radical, he is amateur. I’ve watched some his “trailer fix” videos and they’re just plain awful. His Last Jedi edit looks a bit better, but has this strange choppiness to it. That and YouTube is a terrible platform to work on, most of the comments don’t know a thing about editing.
That being said, completely removing the Holdo Plan subplot for a traitor onboard with Ackbar is a great idea. That question is will it be executed properly. The Lightsaber Duel, on the other hand, sounds cool in theory but completely ruins the entire symbolic point of the fight.
