I'm perfectly fine with there being a sense of "familiarity". Especially since these are supposed to be the "same" people from the first. I watched a panel for "The Strangers" last year at Horror Hound with the original cast...their interpretation of the material was quite interesting. While I myself have a different take, it was cool hearing what they thought/the events that must have led up to this point.
The Strangers 1 was the "game" going too far and concluding. With that notion in mind it would make sense to explore similar tactics, seen in the first, to warrant success. I just hope they manage to make it suspenseful, gripping and harrowing. The first was a slow burn but realistic.
Like I stated in a previous post, I'd take these kind of movies, over the paranormal thrillers, any day. This, to me, is true horror. Exploring what mankind is capable of inflicting on it's own species is fascinating. The most harrowing reason of all is "no motive". I'm tired of the explained. Sometimes evil exists for the sole sake of existing...there doesn't need to be a reason.
Thanks for replying to my question, loki!
