Looks awesome.
EDIT: Also "This one's going after the teen/twilight market", is not correct at all! Twilight fans might see it because Stewart, but it seems the trailer mostly rustled the jimmies of my kind of people; people who like dark fantasy, and gothic stuff (Solomon Kane, LotR, Sleepy Hollow, Pan's Labyrinth etc.).
About, Mirror Mirror. Tarsem himself said it will be "sickeningly kiddie", which I agree it looks like, and it might be a turnoff for me, but the visual side of it the looks neat anyway. If it's "kiddie" like the Princess Bride, it's good, but if it's "kiddie" like [enter a horrible kids movie here], no thanks.
