I much look forward to "Iron Man 2." Freed from the burden of backstory, it could be a movie that fully takes wing. Unfortunately, the new "Iron Man" — Marvel's first attempt at a wholly owned film franchise — doesn't, really. The movie is an origin story, and so before it gets around to a whole lot else, it must first introduce us to billionaire munitions genius Tony Stark and relate to us the details of his swinging, Bond-like lifestyle; his near-mortal injury and capture while on a business visit to war-torn Afghanistan; his wily construction, while in captivity, of a jumbo suit of flame-throwing, high-flying armor; and his subsequent escape, moral turnabout and commitment to fighting evil wherever it may be found. All of this is necessary, of course, but it's terribly time-consuming.
