Having read up on the predictions threads for IM1 and IM2, I am now LOLing with hilarity. All the gloom and doom before the release of the first one, and complaints of underperformance after the release of the second. Honestly, I just hope the movie is badass, because we all know it will deliver fine financially, and I am more concerned about getting a nice full circle feeling to the entire RDJ-IM franchise.
That said, I do hope for a billion, riding on the Avengers fame. Many have said that the movie greatest accomplishment was the balancing of so many superheroes, but it was actually down to preventing RDJ/Tony Stark from running away with the script
