Having seen it three times, I’m more comfortable integrating it into my ranking. I’m going to use letter grades, because I like those better.
The Phantom Menace: C-
Attack of the Clones: D
Revenge of the Sith: D/C-
A New Hope: A
The Empire Strikes Back: A+
Return of the Jedi: B
The Force Awakens: B/B+
Right now I think TFA has a slight edge of ROTJ by virtue of its enthusiasm. There’s just so much gee-whiz vitality across the board there, whereas I’ve always felt that in Jedi everyone except Mark Hamill and Ian McDiarmid is coasting. I’m really not going to be able to do this definitively until I’ve lived with TFA on home video for a year or so, though.
