I finally saw this the other day... And I'm not impressed. Probably my least favorite of the trilogy. I think they wasted so much potential on changing things to meet their vision, so much so that they're completely ruined one of Stark's greatest and deadliest enemies. Spoilers below, turn back now if you don't want to see them...
The Mandarin is an actor??? Seriously?
Worst movie decision I can think of in a long time. I was looking forward to seeing the Mandarin use his Ten Rings of Power against Tony and a huge battle royale between the two. Instead, he's a drunk actor. I seriously almost left the theater at that point. Then there's the Extremis story arc. While I didn't read it in the comics, I do know that Stark had built a suit to directly combat the Extremis-enhanced villains. Tony built his Mark III in a matter of hours, same with most of his suits. He had 42 suits, and none could withstand the Extremis? Come on already. Part of the fun of Iron Man, for me, was seeing Tony come up with new suits on the spot to combat whatever challenge that faced him. I know his house got blown up (probably the only part of the movie I thought was good, seeing Pepper don the suit like that and seeing the struggles), but he had access to Stark Tower and Stark Industries. You're telling me he couldn't have Jarvis start working on specs for an Extremis Armor? I know it adds to the suspense and stuff, but get serious. I did like Cheadle's Rhodey and Iron Patriot, I think they were the best parts in the whole movie. And I can be ok with him not calling in The Avengers on his own, but you can't tell me that S.H.I.E.L.D wasn't keeping tabs on this and wouldn't send SOMEONE to help out, like Black Widow, or Hawkeye, or even Cap to make some sort of cameo. The President gets taken hostage and every military entity at our disposal is just sitting at home?
Sorry, too many holes, too many missed opportunities, for my liking. It wasn't the WORST movie I've ever seen, and I'll probably buy it to complete the trilogy, but definitely missed the mark on this one.
