It is Ultron's warped logic - that mankind is the enemy of the planet - which eggs him on to bring about its extinction. Avengers - Iron Man, Captain America, Thor, Hulk, Black Widow, Hawkeye along with Strucker's experiments - The Maximoff twins; Pietro who has superhuman speed and Wanda, who can manipulate minds and throw energy blasts, all join in to stop Ultron from causing mass destruction, forms the crux of the story.
Though this is an action thriller, there is drama and humour in equal measure. The performances of every character are typical and everyone has a decent amount of screen time to shine. But it is the line-up of new individuals who add to the novelty factor of the film.
