Actually, looking up some stuff on his book on 'Lost Causes', Zizek comes across well (suppose I should read more of him - I just have a knee-jerk hatred of cultural theorists, specially if they're fashionable, but it seems he's an anti-po-mo-cultural theorist, therefore one of the good guys)...he's a lot smarter than Schama, so I'm hoping he'll wipe the floor with him.
