Garry Marshall's Laverne & Shirley hit the ground running. One wrinkle: Despite its spicier tone, ''L&S'' didn't tackle the social issues (race relations, nuclear war). Inexplicably, no EXTRAS. Releasing this show -- which is already sitting in our collective unconscious (and in syndication) -- without outtakes, commentary, audition footage, etc., leaves us with a frustratingly limited view of how a cultural icon looked before anyone even thought of jumping the shark.
