The second series of Farscape expands upon and develops the characters introduced in the ambitious . John Crichton's new nemesis is the deadly Scorpius, replacing Crais, who has taken the living ship Moya's offspring on a voyage into the unknown. Moya's regular crew--Aeryn, Zhaan, Chiana, D'Argo and Rygel--remain as divided and suspicious of each other as ever, yet somehow manage to pull together at times of crisis. The writers continue to exploit the show's gift for surprising as well as emotionally convincing character development, while the CGI effects, prosthetics and state-of-the-art puppetry--courtesy of Jim Henson's Creature Shop--continue to make Farscape the most original-looking SF show on TV. The witty scripts, peppered with postmodern pop-culture references and movie in-jokes, are also a breath of fresh air. Despite some wildly erratic shifts in tone, this is exceptional TV science fiction that continually pushes the accepted boundaries of the genre. --Mark Walker
