We watched IRON MAN last night for the second time, this time on DVD. We enjoyed it as much as we did when we saw it in the theater.
One aspect I focused on more in this viewing: The product placement. I'm of two minds about this. On the one hand, it's obnoxiously blatant in some scenes (a closeup of Stark's Bvlgari watch, or his bag of Burger King cheeseburgers). On the other, some namechecking is necessary to establish that this takes place in something nominally resembling the real world; and to establish Stark's status as a really rich guy who wears and uses all the top brands. (Although as an LA resident, you'd think Stark would have visited a local non-chain burger stand, like Hamburger Habit, for his first cheeseburger after escaping captivity.)
