Ironman 2 , while Downey is similar in both...
has possibly the best sci-fi movie villain of the decade

Mickey Rourke as Ivan Vanko is superb.... brilliant, relentless, yet we still feel for him. And he's far more interesting-complex than Tony Stark.


not since Roy Batty (Rutger Hauer) (Blade Runner) ... can I recall such an interesting, complex villain... one who we still empathized with

there probably are others (in a sci-fi film) but those 2 I couldn't help but love , empathize with. Now that's good writing.
