well, there was none. the guy they've been suspecting all along turns out to be the killer.
i thought in the end the blonde chick would be revealed as the actual killer.
I actually like how they didn't try to shoehorn in a twist. I get the feeling they were aiming more for suspense.
shareI also believe they tried to hint she could be the killer... but that would have been so lame... so I am actually glad they kept Mackey a the killer... but the ending was a surprise and really helped an until then really straigt forward film with a plot that have been used a dozen times before...
shareHow could a teenaged girl be murdering people for a decade?
That would have been really dumb
