The strangers is garbage, very little happens, it's about as disturbing as eating an orange..
I have to say that i really enjoyed "the mist" and the ending is immense.
Not seen the orphanage yet but it is definitely on the list of must see films.
As far as great horror films go there hasn't really been a true classic for years now, if i had to pick one i would say 1408 as i thought that was pretty good.
For true gore you need to see Murder Set Pieces..that will stick with you for life.
