★ ★ ½ Anna Karenina Joe Wright’s adaptation of the Tolstoy classic staggers under the weight of a dazzling, hermetically sealed visual style that fails to connect with our emotions; the entire movie seems to take place in a snow globe. The cast, led by Keira Knightley, is good, although Aaron Taylor-Johnson’s Vronsky may be too much the boy-toy. With Jude Law. (130 min., R) (Ty Burr)
