“Nobody’s Fool” (** out of four) was an occasionally amusing but shrill comedy about a woman (Tika Sumpter) in an online relationship with a man (Mehcad Brooks) who may not be what he appears and all this is complicated by the return of her sister (Tiffany Haddish) who has just gotten home from prison. Fans of Haddish (I’m not) and writer-director Tyler Perry may want to boost rating by a star but regardless, it’s a mixed bag at best and wears out after a while. Whoopi Goldberg adds some laughs as the girl’s mother. Byetheway, this is not a remake of the 1986 Roseanna Arquette comedy although story is somewhat similar.
