Just when you thought both the TV Western and the miniseries were dead, “Comanche Moon” (8 p.m., Sunday, CBS) arrives. The six-hour miniseries airs over three nights (continuing on Tuesday and Wednesday) and marks the final chapter in the “Lonesome Dove” story written by Larry McMurtry.

Like the best miniseries, “Comanche” has something for every taste, including action, sex, romance, intrigue, light comedy and violence. And “Comanche” also offers something rare in the Western genre: an element of camp.

Rachel Griffiths tears up the screen as the out-of-control villainess Inez Scull. In her first scene, she’s seen buying everything in sight in the only emporium in a dusty Austin, Texas. After cornering the market on the finest china, she settles on a new leather whip, just the thing to encourage the servants and slaves. Later, she turns a farm boy into her enthusiastic lover, then tires of him and chases him off the mansion with a six-shooter. Neither “Six Feet Under” nor “Brothers & Sisters” affords Griffiths the red meat she devours here with gusto.

Val Kilmer plays her eccentric husband, the daft Texas Ranger Capt. Inish Scull. Educated in Boston, he barrages his cowboy underlings with oddball aphorisms, such as “A fighting man needs other fighting men to fight!” Kilmer, who once played Jim Morrison in “The Doors,” looks very much like rocker David Crosby here, if you can imagine Crosby channeling Theodore Roosevelt.

“Comanche” commences when Call decides to track his Indian enemies on foot and alone, sending his band of Rangers back to Austin to report to the governor and “stay drunk until I return.” When not fighting horse thieves, an enraged Comanche nation and a Mexican bandit with a sadist’s heart, the Rangers make awkward arrangements with the girls they left behind and try to stay out of the way of Inez, the meanest, hungriest and most strong-willed woman west of the Mississippi.

¢ One of the best sci-fi films of the 1980s, “The Terminator” has inspired at least one big-screen sequel too many. “Terminator: The Sarah Connor Chronicles” (7 p.m., Sunday, Fox), its adaptation for serial television, fits in nicely with Fox’s theme of fear-without-end as exemplified by “Prison Break” and the strike-addled “24.”

Lena Headey stars in the title role as the mother of John Connor (Thomas Dekker), the teenager destined to lead a rebellion against a future world run by robots and computers. As anybody who has seen “Terminator” knows, the sneaky cyborbs keep trying to send killers through time to kill him before he can grow up.

It’s impossible to write much about “Chronicles” without giving away key surprises. The most interesting character to emerge is Cameron (Summer Glau) a blank-faced teen who shares a special bond with John Connor. It’s also safe to say that, even by the standards of “24,” this show is hideously violent for prime time network television.
