Spindly-limbed creature? Check.
Title that doubles as a warning? Check.
Black-and-white ink illustrations that look like they could be pulled from a fake grimoire? Pretty damn specific, and yet, that’s a check.
This isn’t a particularly great trailer. Pretty by the numbers, in fact. But I’m a sucker for the things that I am a sucker for, so it’s a given that I’ll be at least slightly interested in Don’t Knock Twice based just the small sample of it shown here.
There are some elements present here that I’ve come to be wary of over the years, in particular the whole “incredibly powerful supernatural being is summoned by the most mundane action” thing. On one hand, I have a soft spot for such summoning, since Bloody Mary might be the first major fear I can remember in my life, and probably should be a subject of a future Confessions of a Fear Junkie entry. On the other hand, for many stories it makes very little sense, particularly when the supernatural creature is summoned to do someone’s specific bidding. That said, the act of knocking on a door may not be what actually summons our supernatural antagonist at all, so I’ll won’t hold that against the movie just yet.
