'The Host' is very much in the same vein as 'Twilight', and there's clearly a huge fan base out there. But I can't imagine myself being as huge as Robert Pattinson. I'm not sure I could handle that level of fame.
I've heard The Demolitionist described, premise-wise, as 'RoboCop' meets 'The Crow' by way of 'La Femme Nikita'. That, as I see it, could not be more accurate.
