Somebody needs to buy Kristen Stewart an ice cream cone with sprinkles to cheer her somber ass up. The young actress, who has turned in good work elsewhere, is killing the Twilight movies with her sullen, hyperventilating lovesick routine. The Twilight Saga: New Moon is much better than its predecessor, Twilight: Suck Ass!, but it isn’t good enough to recommend. Much of the blame rests on the supple shoulders of Stewart, who seems completely miserable. Robert Pattinson doesn’t help matters much as Edward the moping vampire, who spends most of the film off screen. Taylor Lautner as Jacob the cuddly werewolf has a moment or two that isn’t awful, and that’s just about the best thing I can say about the film.
