I had a pleasant time with this comedy about light witchery and even lighter bitchery. If you like Nicole Kidman, you might enjoy her here (she reminded me of Tuesday Weld), and even if you usually find Will Ferrell obnoxious, you might appreciate him hyping rather than trying to minimize his boorishness. Shirley MacLaine and Michael Caine are a bit less at ease, but the special effects, for once, are witty rather than overblown, and director Nora Ephron, writing with her sister Delia, handles the material with grace and confidence. PG-13, 100 min. (JR)
