Be honest with yourself now. Before Robert Downey Jr.'s snarktacular performance as Iron Man, did you give a crap about Tony Stark? You did not. Six years ago, John Favreau revitalized the comic book movie, showing viewers (and studios) that it was possible for a comic book film to straddle the line between comedy and drama, while bending genres between comedy, action, and sci-fi.
James Gunn's upcoming film is going to revitalize the genre for the next six years, showing viewers (and again, and more importantly, studios) that there's a lot to be offered on the far fringe away from those characters with the iconic logos on their chests.
Marvel remains, indeed, the house of ideas.
