Ended up watching this series over the course of a few nights last week while visiting family. They had watched and enjoyed the previous installment in the anthology and were hyped for the new series. The general consensus was that "Bly Manor" was a disappointment and a major step down from "Hill House".
I thought it started out well, with a slow burn and some creepy moments, but it never really pays off. The last few episodes felt really padded out (especially the flashback episode, which just dragged on forever). The time skipping story structure was interesting in Hannah's episode, but was over-used after that. Overall, I wouldn't recommend this as either a horror or love story. My main source of entertainment was looking for ghosts in the background and laughing at Dani running like she sh*t her pants. I was also excited to see Garth Marenghi show up.
As a side note, there were so many distracting elements in this show: the wardrobe choices were all over the place, as were the accents, particularly Peter's ridiculous Scottish accent.
