It's the opposite for me. I could not be more burnt out on StarWars, when they introduced the force in season 2 I rolled my eyes and it somewhat took me out of it. The main downside of watching Andor is that you have your brain nagging you about eposide 7 making everything that you are watching pointless (the new republic is obliterated after 20-30 years).
I have friends that I can't convince to watch it because they are just too done with that universe in general.
But that's the thing, Andor could be outside of StarWars and just its own thing because the world building that it does on its own is excellent, the premise (empire vs rebellion/revolutionaries) is mostly intemporal.
Someone who appreciates Andor should find it easy to forget Ep7 entirely or understand that it was just a reboot remake alternate history, not "canon".
The Force part was hamfisted. It was clear that they were trying to avoid "midochlorians" but didn't know how it handle it, and didn't spend any time to develop it organically. It felt more like highbrow fanservice connecting Cassian to Luke. It's similar to the Kleya hospital/flashback episode, which could well have been its own 3 episode arc and gotten time to breathe like the S1 prison arc. Since they cut the project down to be 4 3-episode mini seasons after S1, instead of 6+ episodes each, they rushed some story arcs and sublots that end up just being presented as bullet points.
7-9 should basically be taken out of canon. They aren't truly original stories or extension of the existing one - they are just a retelling of 4-6 for a modern audience
And this is exactly where I disagree. Andor does not stand very well on its own outside of SW (and that takes it from great tier to very good for me with the other minor squibbles that I have). If you don't know the lore, things will be less clear and the writing will feel strange at times. FWIW, I have recommended this show to many friends who never watched anything SW, they mostly liked it but found some things odd.
WARNING, SPOILERS
The story is not properly resolved. If you have no SW knowledge, the threat isn't even very clear. Some galaxy government lead by an emperor is building a weapon, shown once. If S2 is the end it's pretty unsatisfying in general. The politics are kind of unclear.
The sacrifice of Mothma is very unclear without a SW background. A senator said something and had to flee to a planet (oversimplified).
Without knowledge of R1, the killing machine super droid is down right comical/a sloppy resolve for things.
Without SW knowledge the (imo) best part of the Imperial machinery, bureaucracy, power hunger also becomes awkward at times and frankly less interesting. Syril is my favorite character and Dedra probably second. I found their arcs great, every single non-SW viewer I talked to found them "boring", "that guy with the annoying mother was strange" and "why did they have to be a couple, that's pretty unimaginative writing" etc.
END SPOILERS
My personal quibbles are that the crashed tie episode was pretty bad filler. I have not heard anyone say anything good about it.
Someone else already mentioned minor technical problems (field scene).
I found Diego Luna's acting ok but not great. It felt wooden at times. To some extend that's subjective but it doesn't compare to the lead acting I have in my personal top tier (Breaking Bad for example)
I watched Andor having not watched much other Star Wars, and with vague memories of A New Hope.
I absolutely loved it. So much that I'm now watching the entirety of Star Wars film and TV in chronological order (I'm in the Clone Wars series now, before the timeline overlaps Revenge of the Sith, and I went out of sequence to watch Rogue One to see the conclusion of the cast from Andor). The full chronology can be found here[1], though I used a bit of JS to extract just the films, tv shows, and video specials as a markdown table to put in Obsidian
So as someone who can say I pretty much didn't have the context you claim is necessary to appreciate Andor, I can tell you that it 100% stands out as a masterpiece to people who are unfamiliar with the rest of the Star Wars lore.
I get that it felt like a bit of a diversion from the main story, but thematically the show is largely about the less palatable realities of being part of a resistance movement. That episode is about the reality that you'll probably end up getting waylaid by squabbling idiots along the way. I think it earns its place in the show.
The crashed tie episode was part of the larger theme in the series to show the progression/evolution of the Rebellion over the years (and why there was the reveal that it took place on Yavin). That said I agree the execution could've been better.
