Saturday night fixture "Empty Nest" says so long forever (not counting the reruns that we'll see for a good long time), with a satisfying two-part finale. "Dr. Quinn, Medicine Woman" dabbles history, and a Disney hit film of the '70s gets a new treatment.
* "Empty Nest" (8 p.m.-9 p.m., WBAL, Channel 11) -- After seven seasons, the series ends its run with a double episode that includes the return of Kristy McNichol, who did four seasons as the daughter of Dr. Weston (Richard Mulligan). A double wedding is in the offing, for both Carol (Dinah Manoff) and Laverne (Park Overall). NBC.
* "Dr. Quinn, Medicine Woman" (8 p.m.-10 p.m., WJZ, Channel 13) -- Was Gen. George Custer a good guy or a bad guy? History remembers the Little Big Horn with some ambiguity, but this two-hour episode returns to an earlier incident, as Dr. Mike (Jane Seymour) and Sully (Joe Lando) try to prevent Custer and his men from attacking a Cheyenne village. CBS.
* "Escape to Witch Mountain" (8 p.m.-10 p.m., WMAR, Channel 2) -- Disney had a hit with the 1975 film of this tile, starring Eddie Albert, Kim Richardson and Ilke Eisenmann. In this remake, Robert Vaughn -- remember "The Man From U.N.C.L.E."? -- plays the wicked millionaire pursuing two psychic children (Erik von Detten and Elisabeth Moss). ABC.
* "Sisters" (9 p.m.-11 p.m., WBAL, Channel 11) -- In the first of two season finale back-to-back episodes, Big Al (Robert Klein) has a heart attack that leaves Alex (Swoosie Kurtz) mayor for a day. Meanwhile, Teddy (Sela Ward) gets involved with Jack Chambers (Philip Casnoff). And later, the sisters and their mates take a vacation to rekindle their relationships. NBC.
* "Tales From the Crypt" (11 p.m.-11:30 p.m., WBFF, Channel 45) -- Shelly Hack, Corey Feldman and Jonathan Banks star in an original new episode, "The Assassin," in which mobsters seeking revenge against a hit man get a surprise. Fox.
* "Tyson" (8 p.m.-10 p.m., HBO) -- You've got to admire the turnaround time on this docudrama. The former heavyweight champ left prison after serving three years for rape just a month ago! Based on a book by Jose Torres, the film stars Michael Jai White as the fighter and Paul Winfield as promoter Don King.
