Time magazine's "20 Films We're Looking Forward To" article perfectly encapsulates - in, coincidentally, a pair of sentences that are exactly long enough to be a tweet, but not if you put quotation marks around them - why I'm not looking forward to Iron Man 3:
"The success of last summer’s Dark Knight Rises proved that we like our superheroes brooding. Iron Man is the latest crusader to get serious."
For fuck's sake.
