Halloweentown
Released in 1998, Halloweentown follows a teen and her younger siblings as they realize they’re descended from witches—Grandma is played by Debbie Reynolds—and visit a parallel-dimension town populated by both friendly and menacing monsters. A string of spooky hijinks lead up to the kids having to save the day; there’s never any doubt that good will prevail, but the setting, sort of “creature-feature lite,” is so endearing it’s no surprise this has become one of the most-beloved Disney Channel Original Movies, spawning a trio of sequels.
