I think this was a good horror movie, which had something new in it that kept it interesting. The general presentation was very good.
The pacing is a slow burn with more and more weird stuff happening as it goes on, which I liked a lot. Being someone who hates jump scares I was glad this one didn't really have any. The horror aspect was well done but some might find it mild maybe, and it was scary.
I like that there seems to be an allegory happening in the background of technology causing people to become more isolated and lonely; which of course is sad but true. The demon could be interpreted as a representation of loneliness perhaps as you get older.
I'm not sure why this one was lower on the ratings, but I think it is underrated and I enjoyed it.
7/10 a good novel horror.
