Had been looking forward to this episode as this is one of my favourite of Lovecraft's short stories. Typically though I was left disappointed. Instead of the nightmarish, hallucinatory tale of other dimensions, child sacrifice and unknowable Alien gods, here we have a rather run of the mill ghost story that only borrows a title, a setting and some characters from the source material, while pretty much ignoring all the interesting details of the source. Given the author's utter disdain for what he saw as the childish notion of 'souls', the afterlife and any form of spirtual redemption this is a very frustrating watch.
Anyway...Rupert Grint ( in very good form) plays a spiritualist desperate to bring back his dead sister and in the house of the title he seems to have found a way to the 'other side' but must now fight off a long dead, vengeful witch and her horrific familiar. As a stand alone horror for those with no knowledge of Lovecraft's wider Mythos this is decent enough, If derivative, slice of scares. If, like me, you were hoping for something a bit more grown up from a series helmed by avid Lovecraft disciple Guillermo Del Toro you will be disappointed and a tiny bit annoyed.
