Too many 'plot devices' by the writer/director in place of coherent storytelling.
What could have been an intriguing story about the paw was turned into a murder/slasher movie, which would not have been terrible if the murders made sense.
1. The villain has Flash-like abilities, no not really fast, but somehow appears wherever he needs to be in a few minutes (plot convenience).
2. The protagonist has the ability to warn people but instead talks in vague circles so the people in danger do not react (plot convenience).
3. Dumbest police ever (again).
4. The movie is about the paw, which is rarely seen. It is almost like they created a slasher movie first then added the paw element as an added twist so that is does not appear like a generic slasher movie (but it is).
5. The person with most screen time is the worst actor in movie. He never exudes any real emotion regardless of situation.
6. Charles S Dutton as the cop was wasted opportunity.
Positive?
Stephen Lang plays his part very well.
