Tony Stark wants to invent something that benefits mankind but instead turns out to be the one responsible for the creation of this dangerous self thinking robot, Ultron. The Avengers must assemble once again to fight this menace that wants to kill all the humans on this planet. But Ultron is powerful and the way he is presented makes you wonder how our heroes can defeat him. Just you wait and see...
What I liked best about Age of Ultron was the fact that all our favorite heroes get equal screen time to show of what they can do. Although the action scenes are great (Iron Man in the Hulkbuster versus Hulk!) the thing that really makes this movie work is the interaction between all the people involved. Stark and Banner, Banner and Black Widow, Hawkeye and Black Widow, Thor and Captain America... like in real life you can see with whom each of them get along best. It's also nice to see that Hawkeye gets a lot of screen time. He even gets the most interesting background story of the bunch. Quicksilver and Scarlet Witch make a great addition to the team (sort of) and there are a lot more cameos in the movie (although I don't think anybody spotted Lou Ferrigno!).
The movie runs about two and a half hours and that's pretty long. It could have been a little bit shorter, but overall I didn't mind. With great action scenes (pay attention to the opening action sequence in which he introduces the Avengers in one mighty shot!), nice humor, a lot of cameos and a satisfying finale writer/director Joss Whedon has everything under control and that pays of.
This year (2015) The Avengers Age of Ultron will shatter all box office records and that will be a fitting reward for giving most Marvel fans and 'normal' moviegoers this big treat. Even Pixar slipped (with Cars 2 and Brave) so everybody's waiting for Marvel to produce a real stinker. Although that day may come, The Avengers part 2 is not the movie that will be responsible for that!
