This is not the superhero movie you expected. Consider an early scene at a local diner: we find Tony Stark (Robert Downey, Jr.) having a beer with his buddy Rhodey (Don Cheadle) as a little child approaches Stark for an autograph. The girl hands him a drawing of Iron Man fighting the Chitauri aliens, the last we saw of him from The Avengers (2012). The picture, however, triggers ill memories of him being whisked off into space and back - helplessly falling into the abyss - causing the one thing we would not expect of our brazen hero: a frightful, demented anxiety attack. Sweaty and shaking, Stark leaps outside the diner and, in a complete tonal turnaround, we find him entering his Iron Man suit adorably parked by the driveway - a deadpan punchline mirroring the movie's audacious traipse towards black comedy. Finally, we have a superhero film as playful with its own tale as Tony Stark is with his own legend.
