After seeing it again I feel comfortable to rank. Keep in mind that nostalgia (and fan edits, to an extent) factor into my ratings for the PT). This is all subject to change depending on my mood of course (except for ANH and ESB, which honestly should be A++ because they are my two favorite movies ever).
TPM: C+
AOTC: C
ROTS: B
ANH: A+
ESB: A+
ROTJ: B+
TFA: A
