Hollywood is still hoping all you Twilight fans will patronize some other tween fantasy series-turned-movie. This one's based on Cassandra Clare's "Buffy the Vampire Slayer" crossed with Harry Potter series. In it, a "special" teenager (Lily Collins from Mirror Mirror) learns she's a "shadowhunter," with mystical abilities to fight demons and vampires and stuff. She teams up with a hot dude (Jamie Campbell Bower from The Twilight Saga) and attends a secret training academy far away from muggles--sorry "mundies" as this film calls them. 130 minutes PG-13.
