“Blue Jean” (** out of four) was a diffuse melodrama set in 1988 in England in which the government under Margaret Thatcher passed a law stigmatizing those in the lesbian and gay community; one such teacher (Rosy McEwen) attempts to hide the fact that she is gay and is forced to live a double life until one of her student finds out and threatens to expose her. Provocative and audacious subject matter holds your attention initially but is too wan and remote to achieve the impact it needs. McEwen’s strong performance is a definite plus but that doesn’t mean you care about her character all that much.
