New Adventures of Old Christine (8pm, CBS) - Last season ended with Richard getting gilted by new Christine, and Barb (Wanda Sykes) getting apprehended at his wedding by a sexy INS agent. Wait, Richard is single and Barb needs an American husband. Hmmmm.... (Can't recommend it, but "Gary Unmarried" follows at 8:30).
Mercy (8pm, NBC) - It's another nurse show, and despite having their own version of McDreamy (James Tupper from "Men in Trees"), reviews are pretty sketchy. The main drama involves a former Iraq war vet nurse (Taylor Schilling, left with Tupper) and her coworkers in a New Jersey hospital.
Law & Order: SVU (9pm, NBC) - Producers promise that this season will be more intense than ever, which is a fairly scary thought. Tonight's episode features Christine Lahti as an Executive ADA assisting in a serial rape case.
Criminal Minds (9pm, CBS) - This premiere picks up where last season ended: Hotch (Thomas Gibson) being shot by the Reaper (C. Thomas Howell).
Modern Family (9pm, ABC) - In a(nother) mockumentary style sitcom, Ed O'Neill plays the patriarch of the Pritchett family. He's divorced from Shelly Long, but remarried to a woman half his age, and his gay son has just adopted a Vietnamese baby with his partner. Hilarity ensues.
Cougar Town (9:30, ABC) - A new comedy that appears to be better than its awful title would indicate. Courtney Cox plays a 40-something struggling with the usual issues of aging: re-entering the dating game, raising a teenage son, arm flab, etc.
Eastwick (10pm, ABC) - A new show based on John Updike's novel and the 1987 movie starring Michelle Pfeiffer. Three New England women (Rebecca Romijn, Jaime Ray Newman, Lindsay Price) discover their witchy powers while keeping a close eye on possible love interest/possible bad guy (Paul Gross).
CSI: NY (10pm, CBS) - Tonight's premiere will answer the question of who got shot at the end of last season's finale episode. Are Mac (Gary Sinise) and Stella (Melina Kanakaredes) both okay?
