That would be saying the audience went to see Kingsley as Mandarin. And not that the audience just wanted to see Iron Man after the Avengers with just as much fun and spectacle, which is what they got and why it's looking to make a billion. A billion isn't a one you're in deal - you need repeated strong weeks to get there which this is looking to have. No way would it beat Avengers, but it's looking to be the # 1 Iron Man movie, # 1 movie of the summer, and get close to what Avengers made. That doesn't happen overnight, that happens over many weeks. Plus, even critics liked it. Joss Whedon looked at the finale action sequence and went, "what am I going to do now?" The audience got what they wanted -- more Iron Man, more War Machine/Iron Patriot, a well crafted story, and a villain who can offer an amazing spectacle. Mandarin didn't sell the movie. LOKI could sell a movie - but not Mandarin. To them, Mandarin was just another face of evil which could be replaced by any face of evil. He's not Loki (Avengers' key villain).
Alot of what marvel has been doing is clever marketing, right down to Whedon's little line there. It's all clever stuff. Alot of IM3's success doesn't come on it's own merit. It's simply the way the industry works. I'm not going to discredit the film completely but if Thor 2 came out 2 months after avengers it'd make "lots of money" regardless of weather it was amazing or just solid.
I'm not saying IM3 sucks(I happen to endorse it). What I'm talking about is the audience and their relationship to a story. Have you ever heard of the "it was all a dream" effect. When the movie is almost over and it ends up the lead was just dreaming the entire thing. It's a divisive device and the issue is entirely objective. I am saying that the stunt they pulled with their marketing and the way it ended up, couldn't have made everyone happy...fan boy or not.
If they redefined the modern joker in this manner. Yes, the audience would simply accept that they got "the joker" but to have him be an actor paid for by the likes of Dagget(or whatever that guys name was), who really has no gripes with the protagonist whatsoever?
Vs a man created in part by the protagonist, obsessed with playing and then destroying him on 3 levels.
Also, I agree Mandarin isn't that big a villain, but let's not kid ourselves into thinking they choose the least known IM3 character they could when it came to name recognition.
All I'm saying is that it was a bold move(and I like bold moves), but at the outset it's the type of direction that can(and does) leave some audiences wanting.
I agree however, 1 billion(even coming off of a 1.5 billion dollar film you are advertising yourself as the direct sequel to) means alot of people liked it...
IM3 did do good amount of international maneuvering though(a chinese version?), I'm curious to see just how well it does domestically in relation to both Avengers and even Batman.
