The Standard Superhero Origin movie (and other movies too):
Introduction to hero
Hero gets his powers.
Introduce villain who has SOME sort of connection to the hero.
Something forces the hero to act heroic.
Hero fights villain and gets his/her butt kicked.
Hero learns something from getting his/her butt kicked.
Villain sets up some big evil thing to happen.
Hero has big fight with villain, and wins.
Sprinkle lightly-heavily with funny and/or emotional interactions with secondary characters.
Cook at 100 degrees for 40 minutes, allow to simmer, serve to fanboys and girls. Feeds several thousand people.
