She knocks her mouthy arrests about with the physical overkill of Dirty Harry. Her family dysfunction has left her so defensive that she doesn't converse so much as interrogate. Caviezel stumbles about like a homeless angel, his sad and tender blue eyes peering up from a battered face, his gentle voice delivering simple questions and innocent responses with childlike directness. When he sees Lopez, his eyes light up like he's had a vision. That would at least explain the oddly ominous one of the first half, the confusing clues left dangling, and the utter lack of a coherent direction.
Dead people sound more interesting.
