“Miss Sloane” (**1/2 out of four) was a hot-and-cold political melodrama about a powerful high-stakes political lobbyist (Jessica Chastain) who becomes involved in a lobbying case involving gun control and finds herself in dangerous moral and legal territory in which she has to question her desire to win and her desire for the truth. Cutthroat story about the wheelings-and-dealings and various muckraking in political ambiguity and the media is interesting and well-directed by John Madden but keeps you at arms length through-out. Chastain’s performance ranges from incisive to aloof, and the same could be said about the movie.
