Y'know, I think this bummed-out superhero thing is catching. Depressed Bat-guy, brooding Spider-dude, even the Man of Steel seems existentially troubled in previews of his most recent incarnation.
And smart-alecky Iron Man? He'd appeared inoculated by Tony Stark's reflexive snark from succumbing to a similar ailment — but even he's having anxiety attacks these days. Ever since that Avengers dust-up with those unpleasant aliens last summer, he's evidently been having trouble sleeping.
Remember that cherry red Chevy Malibu convertible that John Travolta drives in Pulp Fiction? You know the one that he crashes, trying to get help after Uma Thurman overdoses? Did you know it's been missing for 19 years because it was stolen? Well, it's not missing anymore.
