I don't like the PT or the ST, but I do think ROTS is a great movie, and TFA was decent, albiet completely unoriginal and copy of the OT.It's really not though. Both of these films were well reviewed. Very high production value, great practical and digital effects. Directors that know how to get good performances out their solid cast. The Disney era corrected some of the key complaints aired about the prequels, namely how horribly stilted and sterile they had become. What they lacked was a creator's vision which - combined with the relentless schedule - quickly snowballed into a major problem.
There's things to enjoy about the prequels. John Williams absolutely crushed it, and there is a ton of nice design work. They're still mediocre movies though, romanticized now because they were bad in different ways to more recent stuff.
Yes, TFA and TLJ were well reviewed by critics, but they don't represent the view of 99% of people, and are often very wrong.TFA is 7.8/10 on IMDb, while TLJ is 6.9/10 and is very decisive movie.
I'd argue the the ST is much more sterile than the PT, but they are much less stilted.
