McCarthy is at his strongest when the focus is on his characters. He has a real knack for fleshing out his main players and their sketchy backgrounds. Piecing their pasts and relationships together is part of the thrill, and like his debut, he shows no fear in introducing and caring for who we believe to be our leads, only to then have the baton passed to others. The three key actors, Rivera, Sandino Moreno and Rickards, offer real emotional depth in their performances that add weight to the believability of the dread-filled scenario. Nor is it wide of the mark to say the filmmaker’s building of suspense is almost Hitchcockian.
Naya Rivera (Glee) has the most challenging role as Vera, the initially off-putting artist who is reluctant to accept anything from her sister, including money and love. Her character changes the most over the film, from emotional unavailability to demonstrating an almost crusader-like determination to do the right thing.
