Would have been a better plot twist IF...(spoiler)
...If somehow Griffin (Colin Hanks) was revealed to be the killer.
This movie, while not awful, somehow lost me when the killer was revealed far too quickly.
i was fully expecting that - since they make such a big deal out of it being 'local' at the beginning. Surely it was one of the team!
but that would've been too "Cary Elwes in Kiss the Girls" or "Blondie Whatserface in Along Came a Spider". or SWAT. or Mission: Impossible.
