I saw this at an advanced screening yesterday.
Good - Acting, visual effects in general, setting and atmosphere, the pace of the film, the language used by the characters, in particular the fantastically long old-fashioned worRAB used by Weaving's character
Bad - Simplistic and highly predictable plot, The Wolfman's face... sort of like something out of Planet of the Apes
Definitely worth seeing, but you'll forget it soon after.
