Query: When they said 'Best Comic Book Movie of All Time' they weren't kidding!

When I saw Robert Downey Jr in the original Iron Man movie, I thought 'that's how you should do a comic book movie!' But I've got to say, Iron Man has been upstaged, but fortunately it's by himself.What really made the movie? There are so many great lines, many of them delivered by Robert Downey Jr, but all of the Avengers have their moments.If DC Comics ever gets around to doing their rumored Justice League movie set up, then they will have some big shoes to fill.The only downer of note was the dearth of extras on the DVD, compared to the Blu-Ray versions, but of the movie itself, no question is it worth it, even without those.
