Well, @Dreenan, you’re about to get a full dose, so hang onto your hat.
Okay, here goes. And warning, it does get a bit ranty at times:
Episode One: The Duel
It was okay, but I think it was trying far too hard to be artistic.
The art style wasn’t my forte, but it was okay. The story was unoriginal, but not terrible.
My main issues were the always-lit lightsaber, the umbrella lightsaber, and the prevalence of “Sith.”
The lightsaber that always stays lit and must be sheathed in Phrik or Cortosis or something is a cool idea, but it doesn’t make much practical sense. The problem is clearly not in the crystal, but in the mechanism of the saber itself, which should be fairly easily replaced or repaired as it is likely a fault in a single component. Additionally, always staying on means that it’s constantly draining its power cell. If the character is unable to acquire replacement parts, then a jury-rigged fix would be to simply modify the lightsaber such that the power cell is disconnected until he wants to use the saber. Otherwise, there will be times when his saber simply shuts off because it doesn’t have any power. Add to that, a lightsaber that is always on is a threat to everyone and everything. Unlike a sword, it doesn’t take much force to do a lot of damage.
As for the prevalence of Sith, I can remember when there was a rule of two and Sidious ordered Ventress eliminated since she was too much like Dooku’s apprentice. I let them get away with the Inquisitors. After all, it makes sense for the Empire to use fallen Jedi to hunt down Jedi, eliminating any surviving Inquisitors once their usefulness has waned. But the constant addition of new red-saber-wielding Force users bothers me, especially with the hint at the end of the story that he’s killed about a dozen.
I have the same problem with Jedi surviving the purge. I can remember back when it was Yoda, Obi-Wan, and a couple people who soon died, or turned to the dark side and then died. The purge is starting to seem like a really ineffective genocide, and I bet you we have more Jedi confirmed as surviving the purge than we do Jedi confirmed to have been killed in it.
Turning a crystal red is, in canon, a fairly arduous process and requires a decent amount of knowledge. That’s really cool. But their prevalence does not make much sense with that explanation, which frustrates me.
Episode Two: Tatooine Rhapsody
Meh, until we get to the end.
I couldn’t stand the animation style, and chibi Boba Fett made my oil congeal, but it wasn’t so bad. Credit to them that they didn’t have someone escape Fett, considering that it happens far too often for him to be the “best bounty hunter in the galaxy.” I think he is or at least should be, but they will often show “this character is cool!” by having them escape him, which bothers me. Han Solo didn’t even escape him!
(So this one handled that okay.)
The end is whence my exasperation arises.
The “be yourself” song is trite, unoriginal, and unimpressive. I struggle to believe that it would not only electrify every person on Mos Espa (surely they would at least have differing tastes?), but Boba Fett and Jabba the Hutt himself as well! If I were in his place, I’d have hung ALL of them!
The singer has an unpleasant voice, and the content of the song is ludicrous. “Be yourself” is such a terrible message in so many ways, but they miss the sheer irony that this is directed at JABBA THE HUTT whose “self” is not exactly something you want to encourage. “Yes, let’s sing to an intergalactic gangster and mass murderer that he should be himself. That’s a great idea!”
I love rock and metal (it’s pretty much the only music suited for a warplane of my caliber, after all), and this was an affront to all I enjoy. After all, rock at its best can be extremely meaningful and philosophically stimulating. This was the antithesis.
Anyway, moving on…
Episode Three: The Twins
*Exasperated screaming*
Opening shot: *Exasperated screaming* WHY DID YOU JUST SLAP TWO STAR DESTROYERS TOGETHER AND SAY SuPeR WeApOn? That’s not how this works!
Move to starboard bridge, where we witness a classic example of exposition, as the droid proceeds to detail to the girl stuff she obviously already knows, just to clue the idiot viewers into the fact that ThE DoUbLe sTaR DeStRoYeR Is a sUpEr wEaPoN. Yes, we gathered that. Yet another planet destroyer, much wow.
THAT’S NOT HOW KYBER CRYSTALS WORK. They aren’t “sources of immense power,” they can channel, lens, and focus power! And they do it well! But they aren’t sources of power themselves! BWAAGH!
LIGHTSABERS DON’T WORK LIKE THAT!!!
AND YOU CAN’T BREATHE IN SPACE.*
AND WHY DOES HE HAVE AN X-WING? AND WHY DOES IT WORK LIKE THAT? YOU CLEARLY DON’T UNDERSTAND HYPERSPACE!!!
As you can probably tell, I liked literally nothing about it. The whole thing was a disaster of epic proportions, and nothing made sense. The dialogue was clunky and rather absurd, and the situations were absurdist. This is basically everything wrong with Visions crammed into a single episode and cranked up to 10.
*Yes, I know for some of the time they would’ve been within the Star Destroyer’s shield bubble, but I don’t think it works like that, at least not according to what we’ve seen before. Additionally, there were parts where he was totally exposed to vacuum and definitely not within the DISD’s shield bubble.
Episode Four: The Village Bride
What kind of a man uses his granddaughter as a hostage in his stead? That was not only implausible, but completely sickening. Any man who would agree to that deserves in no way to be the chief of the village or tribe or whatever it was.
To quote Don Corleone, “What’s the matter with you? You can act like a man!”
That alone would make me dislike the episode, but all the new-agey “one with nature” hippy Forcey stuff was weird and I just couldn’t get on board with it.
Aside from all that, it was pretty meh. The art was pretty good, though.
Episode Five: The Ninth Jedi
This one was okay. I mostly liked it, except for a few things:
The Ghibli-esque absurdism, as I have already discussed, is not something I feel should have a place in Star Wars. Mainly just the asteroid fishing rods.
Does the Force require no practice anymore? She jumps up on the back of her speeder bike and effortlessly parries blaster bolts while also not crashing into anything. Anakin Skywalker? Sure. A girl who has admittedly no training? No, absolutely not. I miss the old days when, like Luke, you had to work to get good (absent the guiding hand of the Force for the DS-1 shot).
This episode also messed up Kyber crystals: They don’t immediately turn color to match the wielder’s Force proclivities, especially not red. To turn red, kyber crystals must “be made to bleed.”
As for the other colors, my understanding of it is that each crystal has its OWN color, and certain crystals (let’s call them “veins”) certain veins of crystal call to certain sorts of Force users. Guardians etc. get blue, typically, while Consulars tend to get green.
“That’s just the style, it doesn’t affect Canon.”
Sure, but I wish they’d be consistent with Star Wars, particularly because the canonicity of this series is of undetermined degree.
Lastly, Jedi surviving the purge. I mentioned this before, so I’ll only recount it briefly. It happens far too frequently, and turns “nearly every Jedi in the galaxy was wiped out in the purge” to “almost all of the 10,000 Jedi were wiped out in the purge, except for the 9,900 that survived.”
That’s all I have watched so far. I intend to watch The Elder, but I haven’t gotten around to it yet.
crazyness of the settings as a feature, not a bug, which is why SW Visions for me fits right in with no loss of credibility or suspicion of disbelief. 
I would watch sequels to a few. May have to pick up the Ronin novel.
