I would say it was aimed at people with an obsessive knowledge of Jedi lore, but are not locked into a”Jedi are always right” mentality. Two sets with a very small overlap. My partner couldn’t follow it because she wasn’t sufficiently well versed in the Jedi religion.
I think you're confusing a failure of storytelling with where it was aimed.
I don't they intentionally failed to explain the Jedi religion properly, but I think the fragmented way they told the story (which was intentional as a stylistic element) meant that you didn't get what was going on until incredibly late unless you were indeed, a Jedi religion "expert" (in which case you saw this coming miles out), and even when you did potentially get it, they'd fragmented things enough that it could still have been confusing.
There are definitely legitimate criticisms of The Acolyte and I think the most cutting ones revolve around the approach it took to storytelling. The same story told in a more straightforward way I think would have been significant more popular and accessible (and raised less ire from the Gen X crowd). What's particularly sad/funny it probably has the best lightsaber and Force combat that Star Wars has ever done outside a videogame (and even a lot of haters acknowledge that, oddly enough). Unfortunately many of the actual criticisms tended to involve the word "woke" (either literally or by implication) or were just rather silly (like calling out "bad acting" or "bad writing" as if that didn't also apply to The Mandalorian and Ahsoka to a perhaps greater extent, but many of the same people praised on those points).
I don't know if I agree that the overlap is "very small" though - but I do feel like there's a generational divide. People who were absolutely locked in on the OT and thought it was amazing do somewhat tend to have a "Jedi == good guy" viewpoint, which Lucas didn't even really have back then, but is the obvious reading on those movies, and was reflected in the first EU. Whereas people raised more on the PT tend to be like "Jedi == questionable".
(Of course we might not have seen the last of The Acolyte's story threads and characters - I'd be unsurprised to see some of them turn up in future decades, especially in animated shows.)
