“The Hands” is a low-key thriller that only half succeeds in being scary. B.O. prospects locally are so-so. Pic, originally shot as a telepic, would be better off on the small screen.Film is the second in writer/director Richard Hobert’s series illustrating the seven deadly sins. The first, “Spring of Joy,” was a comedy. A seemingly innocent young man, Tomas (Boman Oscarsson), arrives on a small island off the Swedish coast and is slowly taken up by the community. It then appears that he has “magic” hands, with the ability to divine water or oil. In fact, it’s all part of a scam. Pic needs a larger dose of shocks and more rapid narrative style to work as a true suspenser. Performances and tech credits, however, are all good.
