St. Vincent is a rather quiet little movie made remarkable mostly, but not exclusively, by Bill Murray's performance in a basically non-comic role, as a man scraping by on the fringes of society who is suddenly confronted with situations requiring him to do the right thing, whether he feels like it or not.
Melissa McCarthy has many reasons to be happy with her new movie Tammy.
She produced, co-wrote and stars, and her husband co-wrote, directed and takes an important small role as the boss who fires her and starts the whole thing going. McCarthy is also more attractive both in her physical appearance and in the character she plays than she was in either Bridesmaids or The Heat, partly because Tammy is a gentle, people-loving movie without satiric edge or the brutality of a police story.
The Heat is an unusual buddy-cop movie in that the odd couple cops are women-- it's also unusual in being very funny indeed, and has a plot that pretty clearly hangs together, though it does not particularly feature credibility.
