Iron Man is amazing. Stay for the end of the credits. You'll love it (especially if you're a Marvel fanboy). I wasn't so big on the inevitable final, climactic showdown... but it was better than a lot of other movies' obvious, big budget final climactic showdowns. The rest of the movie? Spot fucking on. Seriously.
Heck, I'm even glad I went to see it instead of watching the hours and hours of TV I now have waiting for the weekend (or, perhaps, during a lull at work... will there ever be one???)
That includes new Lost.
Yeah. That good.
