Anyone think Stiles was deliberately acted poorly?
I have been thinking about this, I believe Stiles was deliberately acted poorly and shallow. Having read a lot of horror books such as those Sutter Cane is writing, a female love interest to the main character is always under developed and shallow. Notice that John never delves into her personal life despite the lengthy drive?
I think this is supposed to provide a sense of detachment, that all you are watching is the horror story Sutter Cane wrote, as John realizes in the end at the movie.
