StingingVelvet: The prequels definitely have cheesy bad writing in spots, but it kind of fits the Flash Gordon inspired aesthetic to some degree.
I think the only prequel that sort of has this Flash Gordon vibe is Attack of the Clones. Especially the stuff on the arena near the end. But the writing is just atrocius across all three movies.
StingingVelvet: Last Jedi just had bad-bad writing in spots, trying to be funny or Shakespeare and failing completely at both. I'm not sure which is worse really, but I'd probably put Revenge of the Sith above Last Jedi at least.
I've yet to watch it for a second time, but I can hardly imagine hating it that much upon rewatching, even if I do agree that Last Jedi is definately one of those movies that only get worse and worse the more you think about them (and I had plenty of problems with it already).
StingingVelvet: I liked the other two Disney movies better. Rogue One has obvious plot structure issues from studio interference, but I'd still say it's the best of the three IMO.
Rogue One is defiantely the best one of the new movies so far. I like Last Jedi more than Force Awakens, though not really as a better movie as much as a more interesting movie. Force Awakens is so redundant it's downright tedious to watch. Last Jedi may be bad, but at least it's not as boring (though I will probably fast forward through the casino planet stuff next time I watch it, becuase that shit was near unwatchable).
