Because some people actually are.
That is a very capable horror movie trailer.
But it does not excuse the reaction it evoked in a movie theater. It was rapturous. Like something real was happening. But it wasn't real because Annabelle: Creation isn't real. Were it not part of the juggernaut machine built by James Wan and associates it would be a film that iTunes users would have to scroll to discover. The Conjuring and its sequel are terrific horror films. Yes, they still feature the concussively manipulative jump scares but they're well made. Annabelle movies are the Aaron Norris or Don Swayze versions of the Conjuring films. They're the Peabo Hemsworth of them, or whatever that dude's name is.
This is the world we live in. Familiarity is key. It's why so many books are the latest in a series. It's why so many of everything are easy to digest. It's the world and it's not fine, lest you mistake this for a thinkpiece.
It's just that Annabelle: Creation is that loose marshmallow in the box of Lucky Charms you hear rattling before you throw it away. You consume it because you're entitlement needs nourishment. It's stale. It's bad. But it's a nice diversion before diabetes. That's Annabelle: Creation.
Annabelle looks a little like Alfred E. Newman.
