The Avengers cast promised Age of Ultronwould be bigger and better than the first. Whether it was actually better or not, you can decide for yourself, but they definitely delivered on being bigger. It had evil robots trying to destroy the world! And new superheroes with cool new superhero powers! And Thor (Chris Hemsworth) traipsing around a cave trying to figure out something or another that might have to do with Loki? Or not?
