6. Iron Man 2
The Buzz: After the first Iron Man wowed at Comic Con 2007, it was a foregone conclusion that Jon Favreau, Robert Downey Jr. and co would be back in 2009 with Iron Man 2. They gleefully presented some footage to the adoring crowd, who ate up Favreau's praise that they were the first audience to give the original film a chance.
Regular Audiences: Though Iron Man 2 raked in its budget three-fold at the box office, it's widely regarded by audiences and critics alike as vastly inferior to the original movie, a reminder that placing Scarlet Johansson in a tight outfit is a great way to sell your movie. Though frankly, given the electric presence of Downey Jr. at these things, it's hard to blame the Con's throng of fanboys, really.
