Revised rankings with Rogue One, excluding animated films, TV movies, holiday specials, and other shit like that:

Star Wars - The original, the one that introduced us all to this galaxy and the characters we love most, the only one that works as a standalone, the one with the most rewatch value, the most iconic of them all.
The Empire Strikes Back - Arguably a “better” film than the original technically speaking, only loses the edge because its position in the middle of the trilogy requires you watch both of the others to get the story, and while its “darkness” is in some respects a virtue, it also means it has less charm than the original.
Return of the Jedi - Ewoks are cringe when the focus is on them, but that is overblown (they have less screen time than people think) and the rest of the movie is great - the Jabba sequence is really fun and iconic, the space battle is awesome, and the Emperor scenes are the best of the entire series.
The Force Awakens - Yeah it’s a soft reboot, but it’s a fun soft reboot and it made me feel like a kid watching the originals again so it did its job, and I suspect it will seem better in hindsight as a necessary set-up for the sequels if they are done well. Characters are great too.
Revenge of the Sith - Lots of terrible dialogue but the story itself is not bad, essential even to understanding Vader, the only one of the prequels that really does its job in this regard, and Palpatine is incredible in this movie.
Rogue One - I fell asleep in the theater watching this movie the first time. That’s how boring the whole first hour or so is. Lots of fan service and “member berry” moments (more than TFA), unsettling CGI people, tries too hard to be edgy and “grimdark,” and the characters are terrible, unmemorable, and unrelatable. Plus the soundtrack is by far the worst of the series. (No John Williams in Star Wars is sacrilege.) Still, seeing Vader kick some ass again was nice I guess, and helped recover his reputation a little bit from the whiny emo of the prequels.
Attack of the Clones - The love story is arguably the worst ever put on screen, most of the rest is a boring mess, and the CGI action sequences that were the only things that gave the movie any redeeming value whatsoever have aged terribly. The only thing that makes it better than TPM is that at least it felt like it was made for the teenage crowd rather than the under 10 crowd - no Jar Jar or little kids.
The Phantom Menace - Lots of Jar Jar and little kids, incredibly fucking boring basically all the time, CGI has aged terribly, horrible childish potty humor, the plot makes no sense whatsoever, and it isn’t even essential to the plot of the rest of the series and so might as well not even exist (which is why it is axed in the machete order). The only good thing that came out of it is “Duel of the Fates,” and by that I refer more to the music than the duel itself. Darth Maul isn’t even a good villain; he is all style and no substance.
