My ranking of the films based on how much I enjoy them (or in the case of the PT, how much I can tolerate them):
ESB/ANH
ROTJ/RO
TLJ/TFA
(----)
TPM/ROTS
AOTC
On a more critical list the only real differences would be that ESB is above ANH, RO below ROTJ, and TLJ would probably be a bit higher up. I still haven’t gotten around to re-watch TLJ so it might go further up on both lists in the future.
