It’s love at first look instead of first bite in “Twilight,” a deeply sincere, outright goofy vampire romance for the hot-not-to-trot abstinence set. Based on the foundational book in Stephenie Meyer’s best-selling multivolume series, “The Twilight Saga” (four doorstops and counting), this carefully faithful adaptation traces the sighs and whispers, the shy glances and furious glares of two unlikely teenage lovers who fall into each other’s pale, pale arms amid swirling hormones, raging instincts, high school dramas and oh-so-confusing feelings, like, OMG he’s SO HOT!! Does he like ME?? Will he KILL me??? I don’t CARE!!!

It’s no wonder he looks famished. When Edward first meets Bella, who has moved to Forks to live with her father (Billy Burke), he glowers at her threateningly, his hands clenching into fists. Bella is mystified, and you might be too, if Melissa Rosenberg’s screenplay didn’t turn up the volume as the teenagers grow closer and Edward hints at his true nature. “What if I’m the bad guy?” he asks. (Cue the shrieking virgins.) “I still don’t know if I can control myself,” he later confesses, as someone’s guitar gently weeps. A self-described monster, he has all kinds of cool, superhuman powers (running, leaping, mind-reading), but nothing compares to how he masters his universe: he keeps his fangs in his mouth.
That may make him catnip to anyone with OJD (obsessive Jonas Brothers disorder), but it also means he’s a bore, despite the efforts of the capable and exotically beautiful Mr. Pattinson. (The actor first broke hearts as the martyred Cedric Diggory in the Harry Potter cycle.) Though her filmmaking can be shaky, the director Catherine Hardwicke has an eye for pretty young things and a feel for the private worlds that younger people make for themselves. But she’s working in shackles here. In her best movie, “Lords of Dogtown,” about the birth of the modern skateboard movement, a teenage boy sneaks out at night by slaloming off a roof while holding a surfboard. It’s a blissful declaration of freedom, including freedom from the big parental no.
Faced with the partially clad Bella (who would bite if she could), Edward recoils from her like a distraught Victorian. Like Ms. Hardwicke, the poor boy has been defanged and almost entirely drained. He’s so lifeless, he might as well be dead — oops, he already is.
“Twilight” is rated PG-13 (Parents strongly cautioned). Some violence, little viscera.
