"American Idol" or "Lost" season finales, 7 p.m., Fox and ABC. On the final night of the TV season, here are two shows that have seized viewers' attention. "Idol" does it with energy, optimism and — when we get to the finalists — raw talent. "Lost" does it with richly tangled stories, strong camera work and perfect casting. Now both have two-hour finales, keeping VCRs and Tivo's busy. For "Idol," that requires lots of padding. The important business — announcing whether Bo Bice or Carrie Underwood has been voted the new champion — comes in the final minutes. For "Lost," no padding is ever needed. There are endless stories, as we learn about the crash survivors and their island, which comes complete with a large monster, a scary human and lots of mystery.

Of Note

"Swordfish" (2001), 4 p.m., UPN (KIKU). A computer hacker is kidnapped and forced into an evil scheme. This thriller is known mainly for its terrific cast, with John Travolta, Hugh Jackman, Halle Berry and Don Cheadle.

"Our Fathers," 5 p.m., Showtime. If you missed this superb film in its debut Saturday, catch it now. It brings a richly human dimension to the handling of charges of sexual abuse by Boston-area priests. Brilliant performances by Ted Danson and Brian Dennehy.

"Law & Order," 7 p.m., and "Law & Order: Trial by Jury," 8 p.m., both NBC. Here is a rerun of a two-hour crossover. In the opener, Green (Jesse L. Martin) was wounded while escorting a witness. In the second hour, his temporary replacement (Michael Imperioli of "The Sopranos") joins Fontana (Dennis Farina) in searching for the shooter. The plot is cleverly planned to give Martin time to do the "Rent" movie.

"Amber Frey: Witness for the Prosecution," 8 p.m., CBS. The real-life drama confronting Frey was compelling. She was falling in love with the glib and handsome Scott Peterson; then she learned he was married and his pregnant wife was missing. There's not enough here to fill two hours. The film is partially salvaged by the subtle work of Janel Moloney ("The West Wing") in the title role.

"American Masters: Cary Grant: A Class Apart," 9 p.m., PBS. From his humble beginnings in British vaudeville, Archibald Leach transformed himself into Cary Grant, the elegant man chosen by Premiere magazine as the No. 1 star in movie history.
