“I can’t sleep,” are the words said by the hero who saved New York and arguably one of the most influential people in the world.

After the events that took place in 2012’s “The Avengers,” Robert Downey Jr. returns with another amzing performance in the third installment of the “Iron Man” series. Was this addition worth it?

Tony Stark is well known for his egotistical attitude toward pretty much everything in his life. Up until the events of the first movie, he cared only for himself. While this attitude doesn’t change too much, he learns to accept the responsibility of protecting those around him. In the latest section of the story arc, Stark has to fight an enemy that makes his suit seem, well, weak. He also makes up for poor decisions he made in the past.

He is falling apart and trying to cover it up by building more and more suits (he is up to mk. 42). The only thing that is keeping him together is his girlfriend Pepper Potts, played by Gwyneth Paltrow. Events later in the story force Stark to acknowledge he is only human and needs outside help. In the end, Stark makes a decision that many may be skeptical about, but it shows how far he has come as a character.

The “Iron Man” series has had an ongoing story of Stark during and after the creation of the Ironman suit. The first film in 2008 created an excellent origin story that everybody could get behind. The events of the second film were almost unnecessary. The only lasting impact left by the second film in 2010 is the new arc reactor Stark created. The third and (hopefully) final piece of the story arc has a dramatic amount of development that will have an everlasting impact on the Marvel timeline.

The movie clocks in at 130 minutes and rates in at PG-13 for violence and suggestive themes. It also has a new director, Shane Black, along with Guy Pearce as Aldrich Killian, CEO of Advanced Idea Mechanics or AIM and the other villion.

If you enjoyed the first installment or cool sci-fi action movies, then this is a must-see.
