I keep waiting for this show to stumble but 17 hours in and I’m still hooked by the unusual depth of characterization as well as the series’ ability to maintain dramatic tension and narrative ambiguity. What first seemed to be a potentially hokey amalgamation of Land of the Lost, Lord of the Flies, and Gilligan’s Island has transformed itself into a potent post-9/11 story of human redemption. With its cast of Koreans, Australians, Iraquis and Americans, a crazy French lady and some polar bears; LOST may be the best hour of network television since . . . well, Freaks and Geeks (24’s “wham bam thank you mam” aesthetics and the convoluted machinations of Alias’ Rimbaldi plot do not measure up). Will it, however, be able to sustain itself into a second and third season, or will it flame out spectacularly like Twin Peaks?
