Yeah, the film was pretty neat. Lots of stuff for the fanboys, esp. the SHIELD references, the computer named Jarvis, Jon Favreau as Happy Hogan etc. These films need to be faster, more like Hong Kong action films or the last Bourne thing. Less exposition and logic would be preferable. But the total 1960's Marvel irreverence was finally expressed with Robert fucking Downey Jr. ad-libbing his way through it in a way that is as joyful as Adam West.
Yeah, purists may disagree with me on this, but my gold standard is still Batman 1966, for the pure pleasure of being a human comic book. I can see RDJ saying "Some days you just can't get rid of a bomb" and that is pretty cool.
Later: One reason that this film has a Marvel level of insouciance is that the script came after the art, in the old Marvel style. Favreau was smart to get this, so that after all the elaborate effects, the actors and dialogue are fresh and smartypants. (Well except for the B movie terrorist types.)
