Two series with fantasy elements debut this coming week and both get off to strong creative starts. Fox introduces its new J.J. Abrams-executive-produced show with back-to-back episodes, but only the first hour was available for review. It’s a strong, creative pilot filled with beautiful shots of Alcatraz Island and San Francisco and an intriguing story, too.

“Alcatraz” (8-10 p.m. EST Monday) proceeds from the notion that the night the island prison was shut down in March 1963, its prisoners all disappeared. Now they’re somehow coming back.
