We've seen it happen time and time again.
A hero comes to fruition in the first movie, everything seems right in the world.
A real test shows itself in the second movie putting the hero through their pace.
Then... something goes horribly wrong... a monster... a threat bigger than any Magento or Joker or Doc Ock or Green Goblin... its the threat of the movie studio, who after two run away successes, figure they know better than the people who made the movie how to handle it....
Then we end up with Batnipples,
Emo dancing,
And random character killing,
There are a ton of these movies, but which is the worst of the worst?
