The Strangers theory

[Bojangles]

That's definitely some good points. You also brought up things that I didn't catch while watching this film. I figured The Strangers were someone that they knew, though. I remember watching this in theaters and questioning who it could be. When sack-head took his mask off, the couple looked surprised. Also, Sack-Head was the last to take his mask off, right? If I remember right, one of the girls looked at him for a moment, as he looked back. This scene seemed to me as if there was some unspoken words going on. Like a "Are you sure you're ready to reveal yourself" type of feel.
