If you want to watch interesting TV tonight, you'd better have, get, or visit someone who subscribes to, cable. Broadcast TV tonight is sort of like obesity. It's a big waist.

* "Cinderella . . . Frozen in Time" (8 p.m.-9 p.m., WJZ, Channel 13) -- Dorothy Hamill stars in this new, on-ice staging of the fairy tale classic, which features Lloyd Bridges as the narrator and includes a few twists. Instead of losing a glass slipper, for example, Ms. Hamill's Cinderella is attacked suddenly and cracked in the knee with a club. OK, not really, but can't you just picture it? Nancy Kerrigan as Cinderella, Tonya Harding as one of the wicked stepsisters, and Connie Chung as the fairy godmother? ABC.

* "Winnetka Road" (10 p.m.-11 p.m., WMAR, Channel 2) -- This is the last trip down the "Road" for NBC, unless the network renews it. Next week, "Sisters" is back. NBC.

* "Saturday Night Live" (11:30 p.m.-1 a.m., WMAR, Channel 2) -- Emilio Estevez is the host, Pearl Jam is the musical guest, and here's my advice to the performers and writers of "SNL": Be funnier. Hope that helps. NBC.

Cable

* "The Lifeforce Experiment" (8 p.m.-10 p.m., Sci-Fi) -- Donald Sutherland and Mimi Kuzyk star in this Sci-Fi Channel made-for-TV movie, which has a decent premise and some commendable performances. Mr. Sutherland, with a beard borrowed from a Smith Bros. cough drop box, and Ms. Kuzyk, looking astonishingly like Kate Nelligan, are very good here, in whatamounts to the umpteenth variation on the "Frankenstein" story.
