There's no doubt that NCIS is slick, entertaining prime-time television in every respect: writing, acting, production values, music, and so on. Still, one's appreciation of the show largely depends on the characters' likeability, and that's very much a matter of taste. Gibbs may be a chick magnet, with four former wives and a past relationship with Shepard to prove it, but he's also a taciturn fellow with horrible social skills. DiNozzo's funny and insouciant, but his smugness and incessant razzing of computer nerd Timothy McGee (Sean Murray) soon becomes tiresome, while Shepard is steely and simply unlikeable (the most appealing characters are arguably McCallum's Mallard and Pauley Perrette's mouthy Abby Sciuto, the goth-like forensic expert). Bonus material includes cast and crew commentary on various episodes and a typical assortment of featurettes. --Sam Graham
