My rankings:
ESB
ANH
ROTJ-RO
TLJ-TFA
TPM-ROTS
AOTC
I’m still one the fence about TLJ, so this ranking is likely to change after I’ve seen it again.
(I don’t get all the negativity towards RO. I feel like it’s biggest sin was simply not trying to be the best SW movie ever. It was just a simple spin-off story that tried to entertain, and that to me is a rare virtue in modern Hollywood.)
