Whannell is a super talent, intelligent, passionate film maker and it's very exciting that he had a vision and is seeing it through rather than going "So how can we have a guy get attacked and do the transformation scene we've seen done a dozen times now once more?"
It's cool to see innovation in a story as entrenched as The Wolf Man. And if it's not any good? The ones that came before it still exist and they'll be plenty more 'guy turns into large angry dog' films in the future.
