The prequels sucked. There’s no way to possibly argue they are good or well-made, even if you don’t think they sucked.
The things I like about the prequels are the basic plot points. Palpatine working two sides of a war to his advantage is a bit sophisticated for that sort of film.
All they had to do was write an original plot
Are you sure you want this? Are we sure we want this?
Me personally I want a nearly original plot with a couple of parallels to the OT but with that comes the chance that it will not feel enough like Star Wars which will most likely be the main complaint about Episodes VIII and IX.
