TROS is far better acted, but I would strongly disagree about the movie not being drama-less. It makes anti-dramatic choices at nearly every turn, undercutting things with mounds of exposition, undermining potentially dramatic twists mere scenes later and then ignoring all the potential character drama that could come from it. The climax is so inert because Ben's sudden and improbably flip to the light isn't even explored (does he even have *any* dialogue in the back half of the movie), the whole palpatine thing is just convoluted plot nonsense that actively weakened Rey as a character, and there wasn't even any satisfying action to satisfy on a purely visceral level.
The prequels all have terrible dialogue and wooden acting, but at the very least stuff like revenge of the sith at least attempts to satisfy a dramatic arc that has been developed over the movies, and tries to stage things in ways that progress and have the characters doing stuff beyond a flacid and static confrontation with a subpar plot device. It's a low, low bar but TROS didn't even satisfy that criteria.
