Kick-Ass (2010) was extreme, but at least it was fun.  The 2013 sequel is unnecessarily sick for an action movie, to describe how sick it is would be too obscene for this review.  The son of the bad guy who was killed in the first movie seeks revenge, but the movie does not really focus on this.  It spends too much time on showing Hit-Girl trying to have a normal high school life unsuccessfully, but it really does not fit the story coherently, and wastes her talent.  To make things worse, when a movie attempts to use feces to create a comedic moment, it is in serious trouble.
