CBS (9-11 p.m. ET)
This unnerving, thoughtful four-hour docudrama (the conclusion airs Wednesday) could be a ratings blockbuster. Little-known Broadway actor Powers Boothe plays Jones with a compelling intensity. The superb cast also includes Colleen Dewhurst, Diane Ladd, Ned Beatty, Brad Dourif, Veronica Cartwright, Brenda Vaccaro, LeVar Burton and James Earl Jones. They make the grotesque disaster almost understandable.
