Okay. So I went to see this film the first morning it was out, and i'm not sure what to say about it.
It feels like Mr. Joss Whedon was just trying to re-create it's prequel, the first Avengers. The majority of all the jokes used were just recycled and sometimes used more than once.
Also the creation of Ultron seemed EXTREMELY rushed. There needed to be more information about the creation of his second body. One scene he looks like Tony Stark's trash, then the scene after he looks like a giant metal god.
All together, putting aside my filmmakers point of view. As a Marvel comic book fan, I am very happy with the way the cinematic universe is heading. With all the characters slowly but surely coming together, all for the brawl over the infinity stones!
