Decent. It's just not at all Hill House.
Tied together nicely but I think Hill House was more... hmm.. every piece mattered more in Hill House? You got to see every character in every flashback, so Nell and Stephen and the mom and dad were equally important. Here, not as much - you'd get an entire episode committed to Hannah or the lady of the lake but they weren't all as essential as the few main characters.
The character episodes in Hill House really informed the bigger picture and were entertaining. I don't think that was quite the case here. They weren't quite as informative or quite as entertaining. Not quite as essential. So the pacing felt as deliberate and methodical and more like detours.
Edit: also, way less ghosts! Hill House kept throwing new creepy threats at you. Tall guy, zombie, skeleton in the walls, Poppy, old lady, Bent Neck Lady, etc.
