It probably would have made more, if it had not been for the Pacman-Merichicken fight.
I can tell you that it was very action packed and nostop during the entire movie. However, some of the interactions, especially between Black Widow and Bruce Banner felt somewhat forced and unconvincing, imo.
I have not seen it, but probably will.
Although I did like the first Avengers movie.
It seems like A LOT of these comic book movies (X-Men, Spider Man, Batman, etc....) are making a lot of money at the box office in the last few years.
