This is how I rank them as films standalone.
ANH-4 stars out of 4. Masterpiece.
ESB- 4 stars out of four. Masterpiece.
ROTJ-4 stars out of 4. Simplistic at times serial adventure.
TPM-3.5 stars out of four. Despite numerous narrative flaws this is still a memorable exercise in scifi.
AOTC-2 stars out of four.
ROTS-1.5 stars out of four.
TFA-1.5 stars out of four.But most people simply say I don’t like anything…
Can’t say I agree with your ratings for ROTJ and TPM, but I do have a more positive opinion of TPM than most other members here. It’s the only one of the prequels that feels like a Star Wars movie to me, and despite its many problems, it gave us an awesome lightsaber duel and one of the best soundtracks in the entire franchise.
Maybe I’d like TFA more if they slowed down the pacing a bit and added more exposition to flesh out the story. That wouldn’t solve all its issues, but I think it would help. It begs for an extended cut.
