CBS made a few key changes on its fall schedule, adding five new shows, moving three returning shows and launching a comedy block on Wednesdays.

But CBS's sister network, The CW, has the most buzzed-about new show — a revival of "Beverly Hills, 90210."

Titled simply "90210," it's sort of "The Next Generation" of the 1990-2000 Fox series about high school kids in one of the nation's most exclusive ZIP codes. Other than original cast member Jennie Garth, it's a whole new cast and a new set of writers and producers.

CBS's new shows are:

"The Worst Week'' (Mondays, 8:30 p.m.) is a sitcom about a guy (Kyle Bornheimer) who just can't seem to impress his future in-laws.

"The Mentalist" (Tuesdays, 8 p.m.) is a drama about a psychic turned detective. Simon Baker ("The Guardian") stars.

"Project Gary" (Wednesdays, 7:30 p.m.) is a sitcom about a guy (Jay Mohr) and his ex-wife (Paula Marshall).

"Eleventh Hour" (Thursdays, 9 p.m.) is a drama about a biophysicist (Rufus Sewell of "The Illusionist") who investigates scientific crises and oddities.

"The Ex List" (Fridays, 8 p.m.) is a comedy/drama about a woman (Elizabeth Reaser of "Grey's Anatomy") who is told by a psychic that she's already dated her future husband — and she's got to find him.

For midseason, CBS renewed the sitcom "Rules of Engagement" and will add the drama/murder mystery "Harper's Island."

Canceled shows include "Moonlight," "Jericho," "Shark" and "Cane."

OVER AT THE CW, there are only three new shows for the moment, including "90210." The others are:

"Surviving the Filthy Rich" (Tuesdays, 8 p.m.) is about a live-in tutor (JoAnna Garcia of "Reba') to two wealthy and wild twin sisters in Palm Beach.

"Stylistas" (Wednesdays, 8 p.m.) is a fashion reality show from the producers or "America's Next Top Model." Eleven fashion enthusiasts will vie for a "coveted editorial job" and big prizes.

As previously announced, The CW has sublet its Sunday nights to Media Rights Capital. That company is developing programs for the 6-9 p.m. time slots, which will be announced at a later date.

The CW announced only one midseason replacement show and it isn't new — "Reaper" will return.

Canceled shows include "Smackdown," "Beauty and the Geek," "Life Is Wild" and "Farmer Wants a Wife." "Girlfriends" retired after seven seasons.
