It's the boy-wizard's second year at Hogwarts School of Witchcraft and Wizardry where evil forces have released a vicious serpent into the corridors. In line with JK Rowling's book, the second film is darker than the first. It's perhaps somewhat over-long, but the combination of old-fashioned kids' storytelling and blockbuster budget special effects make for something more pleasing than standard Hollywood eye candy.
