Tropes used in Avengers: Age of Ultron include:

Antagonist Title Does this need pointed out?
Adaptation Distillation Actually has nothing to do with the recent Crisis Crossover and is instead based on based onthe introduction of Ultron and Vision combined with Ultron Unlimited.
Ironic Nursery Tune: The trailer's creepy version of "I've Got No Strings". Way to make use of that Disney ownership Marvel.
Never Trust a Trailer Some scenes from the trailers and previews were changed in the theater cut of the film.
Nice Job Breaking It, Hero: Ultron is Tony Stark's invention, so most of the ensuing chaos and destruction is pretty much his fault.
Re Cut: Arriving on Blu-Ray. To the joy of those who were disappointed with the version released in theaters.
Villains Act, Heroes React: The film explores what happens when the heroes attempt to break the status quo by taking preventative measures against human suffering and loss of life. In a nutshell: it just causes more human suffering and loss of life.
