Juel Taylor makes his directorial debut in the ambitious yet uneven "They Cloned Tyrone." At its best this wild genre mashup feels like what we would get if the Coen brothers made a 1970s blaxploitation movie. Those (and several other) cool influences are impossible to miss. At its shakiest the film has a hard time maintaining any kind of consistent tone. That proves to be more of a problem than you might think.
