Some shows coming up with the new TV season..... Medium (NBC), 9 p.m. New drama premiere. Patricia Arquette portrays an ordinary wife and mother who discovers she can chat with the dead to solve crimes. 24 (Fox), 7 p.m. Fourth season special premiere. Kiefer Sutherland returns as Jack Bauer, but much of the cast has changed. Two-hour premiere is followed by two fresh hours Jan. 10. The series runs straight through without repeats until May. Carnivale (HBO), 10 p.m. Second season premiere. Twelve new episodes are set for the critically acclaimed, but confusing apocalyptic drama. Comment: Final battle between good and evil looms. Added narration waters down complexity. Explorer (National Geographic Channel), 7 p.m. Returning series. New channel, new time and new host — Lisa Ling — for the revamped quality show. OK, this has nothing to do with sci-fi or fantasy but I enjoy these types of shows. Battlestar Galactica (Sci Fi), 8 p.m. Drama series premiere. The fan favorite has been updated for the 21 st century. It stars Edward James Olmos and a swell cast of fresh faces. Point Pleasant (Fox), 8 p.m. New sci-fi drama premiere. Elisabeth Harnois portrays a mysterious teen washed ashore in New Jersey. Then, Fox claims, "all hell breaks loose." Why? Her daddy is Satan, but she doesn’t know that.
