Some my claim that "MacGruber" has suffered the fate of other failed "Saturday Night Live" featured films about reoccurring characters like Stuart Smalley, Pat and a "Night at Roxbury" characters. Why pay for something that one can see for free.
"MacGruber" is a one joke character that writer/actor Will Forte is trying to expand to a 90 minute movie. As the narrative continues, the title character becomes more unlikeable. By the end of the movie, one does not care about the fate of "MacGruber."
