Influences to The Visit?
Remember how Shyamalan said that The Happening was supposed to be like a B-movie in the style of The Birds and Invasion of the Body Snatchers?
Well now having watched The Visit, it almost certainly feels like he was attempting to channel some elements from similar thrillers such as Shadow of a Doubt and The Stepfather into that film, i.e. the idea of a family relative being revealed to actually be a psychopathic killer.
What do you think? Does that sound about right, or is it just me?
