There certainly is a lot going on here for a movie with a two-letter title. Whats up with the bunnies? Who's the lady with the scissors? Who are "us"?
Well, a quick view of the trailer will at least tell you that the "us" in question are a mirror image of the family being terrorized...but wait, before they're revealed they look like the villains in "The Strangers".
So the trailer goes to some spooky stuff on the beach into some type of supernatural home invasion.
Whatever is going on, this trailer hitting was a nice and welcome Xmas gift from the director of "Get Out".
