A monster but what kind ? From the comics he might not be " evil " really...he will probably have that whole light vs dark thing going.
From the trailer it looks like they turned Spidey into Batman complete with Com. Gordon...and the Lizard looks like a scaly Venom with a tail...they should gone more for a were-lizard look or something. Waht is up with MJ being BLONDE !? :?
All in all it seems pretty predictable..but fans will love it I guess.
