LOS ANGELES—In what critics are calling a hotly anticipated television “showdown,” Monday night will see the debuts of four separate adaptations of Washington Irving’s 1820 short story “The Legend Of Sleepy Hollow,” including Fox’s Sleepy Hollow, HBO’s Ichabod, TNT’s Headless Horseman, and Showtime’s Cloaked Rider. “Fans of gothic melodrama and classic Americana have their pick of the litter tonight, but only time will tell if they flock to the gritty realism of David Milch’s Ichabod or TNT’s sci-fi depiction of Sleepy Hollow as a futuristic, crime-ridden metropolis,” said Los Angeles Times television critic Mary McNamara of the litany of shows that all followed last year’s release of the BBC drama Mr. Crane. “On the other hand, many viewers could find themselves drawn to Showtime’s Cloaked Rider, starring Toni Collette as the first-ever female Headless Horseman. Only time will tell which show will come out on top.” McNamara noted that all four shows could lose a significant amount of viewers to NBC’s Young Van Winkle, debuting tonight in the same time slot.
