Bruce Willis plays a security guard who discovers he has supernatural powers after a traumatic accident in M. Night Shyamalan’s Unbreakable (B). Willis is charismatic and emotive opposite a  mesmerizing Samuel L. Jackson as a mysterious mentor. The writer/director’s trademark twists and turns are not quite as revelatory as his Sixth Sense, but he vanquishes himself nicely with judiciously paced thrills and intrigue.
