MAY IS THE TIME OF YEAR WHEN A number of long-running series leave the airwaves. As L.A. Law adjourns (Thurs., May 19, 10 p.m. ET) with an episode in which senior partner Leland McKenzie (Richard Dysart) makes a startling announcement, the obvious conclusion is that the series overstayed its welcome by about three seasons. But let us remember the good times in the '80s when this was the freshest and most vibrant show on television.
Star Trek: The Next Generation, on the other hand, has maintained warp speed for seven seasons. The syndicated hit makes its final voyage this week (check local listings) during which Captain Picard (Patrick Stewart) comes unstuck in time. That facilitates the return of old shipmates and tormentors and provides a view of Jean-Luc's eventual Cincinnatus-like retirement. The two-hour special delivers some light romance, some heavy physics and a wonderful sense of closure.
