Just watched all nine episodes of Star Wars: Visions on Disney+, and they were of mixed quality ranging all the way from viciously good to painfully bad. I was previously quite excited about this series since I like both Star Wars and anime, and the fact that all episodes would be 100% written and animated by Japanese studios seemed like a good sign.
None of them are supposed to be canon, but rather "imaginations" of Star Wars in alternate universes, and I'm both disappointed and relieved that Lucasfilm went for this route. Because at one hand, you've got these great stories that introduces new concepts and unique ideas that's never been done in Star Wars before. However, you've also got stories that break more lore than a 12 year old fanfic writer, and they don't feel "Star Warsy" at all. What all episodes have in common is that they're all deeply influenced by Japanese culture and aesthetics, and some episodes pull this off better than *ahem* others. What I mean by that is that you can mix Japanese stuff with Star Wars, they actually go pretty well together, but some episodes feel more like random Japanese anime shows where some fan decided to photoshop Star Wars elements into the background. It's like putting lightsaber effects on the pirates' swords in Pirates of the Caribbean - it may look like Star Wars but it's clearly not.
The best episode is ironically also the first one, "The Duel" a black-and-white animation using a sketchbook aesthetic that sets a bold and grounded tone. The characters are fascinating and reckless, it introduces new interesting ideas, and the fight scenes blew my mind away. I also really enjoyed both "The Village Bride" and "The Elder", the first one manages to blend Japanese culture with Star Wars in an excellent way, the latter manages to feel like a believable canon prequel story to The Phantom Menace.
The worst episode is either "Tatooine Rhapsody" which is silly, unfunny, and poorly animated, or "T0-B1" which is just a mish-mash of stuff that makes no sense.
