Saw it. Meh. It's less silly than the first one; the weapons are, on the whole, more down to earth than the lasers and nanites and such from the first. There is an over-engined VTOL transport and an ugly helicopter with some oddly placed jet engines, and a number of tanks. Good ol' fashioned firearms for the most part.
As for the Rods From God: Wrong, wrong, wrong. Just about everything about their description and effects is just... wrong. Such things do *not* have the impact of nuclear weapons. Great for taking out tanks or even ships, but won't do diddly to cities.
Best thing about the movie: Jonathan Pryce must've had a ball playing the bad guy.
I was misinformed about "Duke's" revised role.
