Ooh boy, hard to rate, especially given how many EU books I've consumed, but I'll give this a shot.
Skywalker Saga:
The Phantom Menace: 5/10, not a particularly exciting movie in the grand scheme of the universe, with the only notable scenes being the podrace and the duel of the fates. However, I don't think it's as bad as many say, the political storyline does have a bit of intrigue to it, especially if you've read certain books from the EU.
Attack of the Clones: 6/10, this might be a somewhat controversial opinion, placing this one so high up. I find AotC to be a generally good movie that suffers significantly from the Anakin-Padme love story. Excluding this subplot, which could itself be salvageable if it had better dialogue and better setup, AotC has many elements that make up an otherwise good Star Wars movie: great action scenes, fun character interactions, witty banter, and a variety of interesting environments/species.
Revenge of the Sith: 9/10, the best movie outside of the original trilogy, by a long shot. Everything the prequels have built up to culminates in a surprisingly satisfactory manner, and the elements and narrative style built in the first two prequels really shine in this one. RotS is memeable through and through because of its dialogue, which gives it great rewatch potential and provides it with some levity amidst the intensely dark narrative. Also, the twin duels of Anakin vs. Obi-Wan and Yoda vs. the Emperor is one of the best scenes of the whole series.
A New Hope: 8.5/10, the one that started it all. ANH is a force (pun intended) to be reckoned with in its own right; it is, after all, the movie that spawned the universe. Its spin on the David vs. Goliath tail is well executed, in a time before the story became too cliche. Both factions are compelling in this movie, with characters on both sides drawing a viewer in. It does slightly lose out to its successor, however, simply because it has to spend more time developing a world, unlike ESB.
The Empire Strikes Back: 9.5/10, the closest thing we're likely to ever get to a perfect Star Wars movie, and indeed, a pillar of the sci-fi movie genre in its own right. No Star Wars movie handles its characters or dialogue nearly as well as ESB does, while also effortlessly mixing in philosophy, space adventure, personal intrigue, action, and family drama. Really could not think of any complaints for this movie in a specific sense, this is just Star Wars at its peak.
Return of the Jedi: 8/10, the climax of the strongest Star Wars trilogy...but not the strongest climax overall. This movie would've done well to go all in for its action and character drama, which are the elements that are best in this movie. It suffers slightly from having too much screentime at Jabba's/on Endor pre-battle. Even though it wouldn't have really fit with the overall storytelling method of the trilogy, it might've been fun to see the famous Bothans collecting intel on the Death Star.
The Force Awakens: 5.5/10, ANH redux...not really...but kinda. The parallels here are unmistakable, and hard to ignore in the context of the story as a whole. The characters here are overall better than at any other point in the sequel trilogy, so that's one point in this movie's favor.
The Last Jedi: 3.5/10, this movie was not very good, to say the least. Character interactions are weak amongst a trilogy with weak character interactions overall; the interactions of Kylo and Rey carry this movie, though there was definitely a missed opportunity in electing not to have them team up. Alas. Otherwise, this movie doesn't offer a whole lot in terms of positive content.
The Rise of Skywalker: 6/10, Ben died from carrying this trilogy on his shoulders. This movie is not particularly good in an objective sense, partially owing to all the backtracking that needed to be done from TLJ. Once again, characters are not a strong point of this movie, particularly the newer ones.
Other Movies:
Solo: 6.5/10, a decent action flick. I don't like it as much as the EU origin story for Han, but it's still a fun watch nonetheless. I also really enjoy the continuity this movie has with other elements of the universe.
Rogue One: 8/10, the best movie made since Disney took over. Even though we largely know going into the movie that all of these characters will have to die, they're still the best movie characters of any of the new ones. This movie packs some major emotional weight, it offers a strong portrayal of the lead-up to ANH, and the closing scene with the escape from Scarif and Vader attacking the rebels...need I say more?
I might come back and do other materials later.
