The first three are obvious, because the fans did not know what to expect:
Star Wars (1977)
The Empire strikes back (1980)
Return of the Jedi (1983)
Star Wars Episode I - The Phantom Menace (1999)
–> The story unfolded like no one expected …i mean Midichlorians? No fan-service here, move along.
Star Wars The Last Jedi (2017)
–> Again the story unfolded like no one expected. Johnson did not care about the fans. No fan-service here, move along.
SW Movies, that were developed & executed WITH the fans in mind:
Star Wars Episode II - Attack of the Clones (2002)
–> Lucas did some course correction here in order to please/calm the fans after TPM. More action & light saber fights, reducing Jar Jars role, injecting OT elements such as the Clones (visual similar to OT Stormtroopers), Tatooine homestead and Jango Jett (visual similar to OT Boba Fett).
Star Wars Episode III - Revenge of the Sith (2005)
–> Lucas continued pleasing the fans: Scaling back Jar Jar so that he was barely in the movie, again lots of light saber fights, Emperor gets his ROTJ face, the famous Tantive IV corridor, X-Wing precursors and Death Star I being build. In general lots of winks to Episode IV. Some elements were necessary for the story (Anakin VS Obi-Wan) some were not (Emperor VS Yoda, the most obvious fan service element imo).
Star Wars The Force Awakens (2015)
–> Well, we all know what happened here. Unoriginal Episode IV Copy or paying honorable tribute to Episode IV? You have to decide for youself.
Rogue One - A Star War Story (2016)
–> That one is obvious imo. Allowedly, it is linked very close to Episode IV, so there should be some OT elements, but … LOOOOOOOOOTS of them were too distracting & unnecessary. Fan Service everywhere.
Solo - A Star Wars Story (2018
–> This one could have a been a fan service mess too, but it wasn’t. Again like ROTS you need to have some necessary elements if you want to tell a an origin story about Han Solo (like Han meets Chewie). But on the other side: NO Jabba the Hutt, NO Tatooine cantina, NO Greedo, NO Mynoks, NO Ord Mantell, NO Jedi, NO Darth Vader, NO Death Star, NO Rancor, NO Boba Fett and NO Slave I in this film. They could have … but they did’nt do it.
