I would start off that the Dark Knight was a more realistic take on batman where it deviated a lot from the comic books. For Iron Man 3, I think Shane Black just used the large amount comic book material he had of the Mandarin, who btw is Ironman's arch nemesis, and just use to wipe his ass.

Firstly, I would say that I somewhat enjoyed how they made Tony Stark scared about the prospect of aliens and another world because of his avengers wormhole incident. I also enjoyed that Ben Kingsley, a really well-known and credited actor, was playing the Mandarin. The set up for the Mandarin as just excellent. I liked how they made him really evil and just all round horrible man, with no care for humans.

However, my compliments end there because we find out that the 'Mandarin' is just some dumbass named Trevor. I mean seriously? You needed Gandhi for that? And btw if they wanted to go that direction of misleading the audience, then they should've done the same thing from batman begins. Replace one Mandarin with another Mandarin like replace one Ra's Al Ghul with the real Ra's Al Ghul. And many people would argue that Guy Pearce's character said he was the Mandarin. I wouldn't take it as if he meant that he was the Mandarin from the comics with the ten rings and all. I would take it as if he meant that he was responsible for all the threats and attacks not the useless Trevor. Another complaint I have is that Tony Stark wasn't smart in this movie as he is normally is. We are told in the film that he is smart but he made so many stupid decisions like: 1. Giving his address to the enemy 2. Not knowing that there is a missile flying towards his mansion until he sees it on the news. 3. Not using his 42 Iron man suits against those helicopters shooting at his house 4. And only using his 42 Iron man suits on an oil tanker (yeah that's safe) 5. Making Iron man suits that crumple like tin foil but apparently can withstand Thor's Hammer? (Technically inconsistency in the storyline) 6. The president not using the Iron Patriot suit to fly to safety when he is hung(technically the president's idiocy) or not having JARVIS remotely fly the suit to safety.

To be honest, the only point to this film is that Iron Man is a major source of income to Disney Marvel and they need a way to continue from the avengers. So those who want to watch this film....don't watch it. Just don't watch it.
