Definitely the best horror I have seen for ages, certainly number one for this year.
I'm not often compelled to write reviews, but this show deserves it. The Haunting of Hill House is billed as a horror and it certainly has elements of Horror in it, but at its heart it's a story about coping with trauma. I needed to take breaks from watching the show, not because I was scared, but because the raw emotions were too much to take in large doses. This is the story of a family ripped to shreds and shoved back together only to find that their pieces no longer fit. Their jagged, broken edges causing each other undue pain and agony as they asses who they've become in light of what they have (or have not) seen. I ached for this family to find closure in a way I never would have anticipated. Even if you do spot the twists coming, it's worth the ride to watch this family fumble through the dark in search of resolution. I'd go so far even to say that seeing the twists coming makes them all the more painful.
Don't be deterred by the marketing; even the faint of heart can enjoy this, provided you have enough kleenex.
