Something was particularly missing in this installment. I felt they used many characters that just weren't needed. For example, I just did not see the purpose of Johansson's character. The plot was well themed but it lacked direction at certain intervals. I kept on reminding myself that this is a comic book movie, this is a comic book movie...But so was Iron Man. The director tried too hard to make it good but in the end it just lacked a strong plot that made the first one so good. Also, the bull technology nonsense that they kept on talking about just made my head spin. So many plot holes, so many unnecessary scenes and characters. In the end, the director just created a summer blockbuster; in nowhere would this ever be considered a classic.
