“Witness Marks”
May have been the scariest jump scare I have ever seen.
I was so engaged with the angry conversation going on between Theo and Shirley that I never once even considered that there would be something scary happen.
And when the ghostly figure of Nell screeched from the back seat, I literally screamed out. That rarely happened. The show got me good.
Prior to that, I was thinking what a group of douchebags these Crain kids were. I would go as far as to say that I really have grown to dislike both Steven and Shirley and their obnoxiousness.
I knew immediately that Luke was heading to the house. I am not sure why no one else thought of that right away, especially considering the weirdness that had been going on around the funeral parlor (last episode).
The whole knocking and doorbell ringing at that funeral parlor was creepy too, and it only served to make me dislike Shirley more. Dismissing this impossibility as kids playing pranks is just so short sighted that she was more embracing her own anger and resentments than able to see what was going on.
Then, the monologue from Theo after the jump scare was heartbreaking. The whole “I felt nothing” stuff was tough to listen to and, seemingly, finally got through the exterior of her sister.
By the way, last week’s episode had Hugh’s flashback heading through the Red Door, but nothing was mentioned or shown about that this week. That did not upset me as what we got was so excellent. Our flashback was Steven fixing up an old vanity for his mom. This was an important memory for Steven because it was proof for him about his mother’s madness, instead of one more haunted item in the Hill House.
Luke at the Hill House failing to light it on fire, only to be confronted by a vision of his mother in a red dress at the top of the stairs and the arrival of Rotten Polly, the owner of the said vanity.
There are two more episodes remaining and this series is absolutely hitting its stride. After this episode ended, which was the shortest run time of the series, I really wanted more.
