I really dug it too. Midnight Mass remains my favorite of these shows, and Hill House is probably a step above this one (though I haven't seen that one since release and should probably refresh myself on it one of these days), but this is on par with or perhaps a bit better than Bly Manor.
Felt weird seeing Poe transplanted to a contemporary setting like this and I still maintain that these stories/poems work best in a Gothic, period setting, but I do overall quite like what Flanagn and his team have done here. There's a sort of trashy soap opera angle to the overall dynamic of the central Usher family and the way they interact that I wasn't expecting, and I found that actually really worked in the show's favor.
