Thanks to Downey’s genius, Iron Man 3 is equally terrific, whether Tony’s fending off an army of villains or bantering with a kid in a shed on a cold, snowy night.

A madly creative, darkly comical, and fiendishly self-aware actioner with muscle to spare.

Besides rehabbing a hero who overcomes anxiety to save the world and defeat the terror-industrial complex by the simple matter of cloning his body armor, the movie proves that there’s still intelligent life on Planet Marvel. As you’re propelled out of the theater on IM3's hydraulic lift of pleasures, you’re likely to say, “That is how it’s done.”

Iron Man 3 is smart, funny and spectacular.
—Peter Bradshaw The Guardian

Stuff blows up and then more stuff blows up because that’s what happens when diversions like this hit movie screens around this time of year: chaos reigns and then some guy cleans it up.
