It should probably be noted before you watch the above that Patton Oswalt plays a Marvel character(s) in Marvel's Agents Of S.H.I.E.L.D.
Of course that doesn't man he's biased, as Patton Oswalt answers fan questions ranging from his thoughts on Spider-Man entering the Marvel Cinematic Universe, to the new Star Wars, to a Matrix/Terminator/Robocop movie, to ripping apart the gritty and serious tone of the new DC movies, to favorite comic book movie, and the superhero he would like to play.
The DC rant hits at about the 4 minute mark.
"God damn it guys," Oswalt offered. "Stop with the brooding! The only one who gets to brood is Batman! It only works if he's the one brooding guy! They can't all be brooding! God damn it."
