One of the best series and you'll not get bored as many times you watch it.
You'll experience story of each character deeply...
I've seen conjuring, conjuring 2, Annabelle,etc like this and they were all great but the story and direction of Haunting of Hill House will instantly connects you on deeper level.
...and also you can binge watch it in short amount of time...
One of the best storytelling and cinematography...
Overall 10/10
Tip: after watching it completely don't forget to watch fan theories of it (one of them is actually true).. you'll love it and definitely get goosebumps !..
