The Empire Strikes Back (I can’t even explain why: this is the perfect sequel as well as the perfect movie: entertaining, intelligent, mythological, deep, moving, funny, an infinite replay value…)
Star Wars A New Hope (almost as good as its first sequel, a very hard call to rank it second place)
Return of the Jedi (the confrontation with the Emperor is truly great, the Jabba’s opening scenes are pure swashbuckling fun, the space battle is magnificent: just frustrating this is a rehash of ANH with dull moments and poor characters. Would have love this scene to make its way in the final cut: https://www.youtube.com/watch?v=gT-ZsR2P8dU (without the “scum” line))
The Force Awakens (mediocre, albeit entertaining and with the first 30 minutes very nicely done. Sadly, the characters, especially Rey - who masters the force in a minute because the script needs it… -, are not interesting, and fan service has its narrative limits).
Revenge of the Sith (well, I like the global aesthetic and a few sequences. Williams score is a masterpiece, but the key scenes are failed in almost every way possible) (with a proper edit, it would be ranked a little bit higher than TFA I think)
The Phantom Menace (not that bad and as about the same quality as ROTS - great score, the Qui Gon Jin lead character is fine, the overall plot is interesting -, but overwhelmed with bad taste jokes, confused plot elements, pointless sequences, and questionable designs)
The Attack of the Clones (this one is so bad on every level, I don’t understand how this is even possible to miss an opportunity so much. I would save most of the Kamino’s scenes and the Tusken massacre. Even the score got mixed up: Yoda’s theme used for Anakin in action, Darth Maul’s theme used for Anakin on a bike, Darth Vader’s theme used for the Clone Troopers and the Republic Army, Trade Federation’s droid army theme for the Separatist’s droid army… : not very wagnerian…).

If it had been a movie, I would have ranked Tartakowsky “Clone Wars” fourth, between Episode VI and Episode VII.
