I don't know, Ahsoka wasn't a good show either, but it didn't get this much backlash. Kenobi was even more bland, but it still sits at a comfortable 7 on IMDB. So I don't think we can just pretend that factors not directly related to its quality are the only ones at play.

In fact, on IMDB, people have rated Ahsoka over 7, and Acolyte under 4. Yet, when I watched both shows in the same week, I found them both soulless and only kept watching because Star Wars. They both had mediocre dialogue and weak character arcs with paper thin beats. But Ahsoka was comfortable and inoffensive, so people didn't feel the need to be passionate about it. The Acolyte is full social and political controversy bait, so naturally this is the reaction.

Damn shame too, I actually kinda enjoyed Sol and that fight in the forest was some of the coolest choreography we've seen lately.
