Avengers: Age of Ultron is everything one may expect, in line with the previous The Avengers (2012) movie. It is entertaining and has spectacular CG as usual. I also like the part about the past and fears of the superheroes, especially the background of the Black Widow.
However, the movie does not show exactly how they overcome their fears. In the case of Thor, we see him actually did something in reaction of it, but this sequence and why he needs help from a certain individual are not well explained at all. One of the new characters is The Vision – given his nature he should be really powerful, but his actual contribution is rather limited. As stated it is an entertaining movie, but I feel that it has the potential to be much better if the plot deficiencies are corrected. Captain America: The Winter Soldier (2014) is still a better movie.
