There's something special about the vulnerability of Tony Stark. He's crass, narcissistic and a million other things, but still susceptible to all of the same things that may bring down you or I. That's what makes this character so believable. He isn't perfect, no matter how many times he tells you he is. Iron Man 3 digs deeper into the brain of Tony Stark and gives you a better look at what gets to him.
I think the story of Iron Man 3 might be a little thinner than the previous two, but it's just as, if not more, entertaining. The special effects are incredible. It's amazing how technology has advanced in just the few years between the first and third films. Where the film lacks in story, it makes up for it in action and explosions. I'd say Iron Man 3 is the most action packed of the bunch.
Robert Downey Jr. has created a character that will go down in history as one of the most iconic characters in Hollywood history. Another classic actor, Ben Kingsley, joins the cast as the Mandarin. Guy Pearce and Rebecca Hall round out another star studded cast. This is a very solid film and worthy of your money. Don't waste your money on going to see it in 3D, though. It's not worth it. And make sure you stay through the credits. As with all Marvel films, there's a little clip at the end for you.
