I for one, HATE these types of movies. It's torture porn, and it's cinema at its worst and most vile. Saw, Hostel, Captivity, etc. are all crap.
I dont really see it as torture porn, I hate Saw, Hostel and those kind of movies, however: the Strangers seems like it's leaning more towards the Amytiville Horror (1975) and Halloween (1978), those classics. There are numerous similarities between The Strangers and Halloween.
-Masks (obviously)
-The antagonist stalking the protagonist
-The "Final Girl" complex (what makes slasher movies what slasher movies are)
-Light use of gore, not too much, not too little
As you can see, it's merely a slasher film, And the atmosphere of it kind of reminds me of The Amytiville Horror. I don't know, I'm personally looking forward to it. May 30th is when it comes out by the way.
Also, back on topic, Wikipedia says it was based on the Keddie Resort Murders, and Manson murders.
