I give TLJ 9.5/10.
Revised rankings:
Tier 1:
ESB
SW
TLJ
Tier 2:
ROTJ
TFA
Tier 3:
ROTS
RO
Tier 4:
TPM
AOTC
Really the bottom two tiers are so bad their differences barely even matter. They ALL suck in their own special way. Also I go back and forth on whether I think ESB or SW is the best and whether AOTC or TPM is the worst.
