The movie's plot showed how Tony Stark became who he is,and how he became Iron Man. It showed how,regardless of your status in life,you can experience life-altering events that can make you better person. I think it is safe to say,another movie will be in the works.If so, Iron Man can start to fight his villains like Mandarin,Yellow Claw,The Melter,The Mole Man,etc..The scene where Terence Howard looked at "Gold Iron Man suit",and said "Next Time",may be door opener for next movie.
