Prison Cell
"Iron Man 2" is a polished, high-octane sequel, not as good as the original but building once again on a quirky performance by Robert Downey Jr. The superhero genre doesn't necessarily require good acting, but when it's there (as in "Iron Man" and "The Dark Knight"), that takes it up a level. Downey here gives us a Tony Stark who is cockier and more egotistical than ever. Or, and here's the key, he seems to be.
