The Phantom Menace - A decent title that evokes an important part of the film, and seems to imply its role as a sort of prologue or intro to a series. It doesn’t sound terribly interesting, though. If my fan edits had to stick with the original title for only one prequel film, it’d be this one.
Attack of the Clones - “‘Ats a horrible title!” Sounds dumb and doesn’t really reflect the film very well. Implies the clones are an enemy force that is invading. Perhaps my least favorite title. “The Clone War(s)” would’ve been much better.
Revenge of the Sith - I don’t like this title, because it doesn’t really get at the essence of the film. We don’t really know anything about the backstory of the Sith, so their revenge doesn’t seem compelling. It’s more about the fall of Anakin and/or the Republic. Seems like it is just there to rhyme with ROTJ or redeem the “revenge” that was dropped from that film’s title. I feel my edit’s “Labyrinth of Evil” (culled from a Luceno EU novel) fits better in getting at the heart of the film’s story.
A New Hope - It’s a very “meh” title. Not compelling, and only exists retroactively to a much better title of “STAR WARS.” It’s fine, and doesn’t put off a new audience with any proper nouns they wouldn’t know about.
The Empire Strikes Back - It’s pulpy, and it ropes audiences in with an inkling that this story will continue a story rather than recreate the original. “Splinter of the Mind’s Eye” could’ve worked as a title, but might have been too out-there. Very good title, though only partially gets at the film’s essence.
Return of the Jedi - One of the best titles, and one that has a dual meaning. Alludes to ‘Return of the King’ and does a good job only tipping off the ending a little bit. No complaints about this one. It gives the impression that the good guys win, but leaves it as a surprise that the bad guy gets redeemed.
The Force Awakens - Excelling title, both for the story and the film’s significance in the real world. Is even referenced in the next movie. Very good.
The Last Jedi - Another title very fitting for its movie and story. Gives a startling implication without lying, tantalizing.
The Rise of Skywalker - This title does capture the film’s gist somewhat, but in a way similar to “Finding Nemo” in that it tips a little too strongly the ending. It struck me as a confusing title going in, what it would mean. It made the final lines of the film, which would’ve been cheesy regardless of the film that built up to it, visible a mile away.
So out of the group, I’d pick ROTJ, TFA, and TLJ as my favorite titles, in that order.
