TELEVISON NETWORKS SPEND MANY months and millions of dollars coming up with a new season of shows. Then, within a matter of weeks, they learn what's working and what isn't. One program - NBC's Tucker, starring Married...With Children's Katey Sagal - has already been yanked after only four airings and replaced on Monday nights at 8:30 with yet another edition of Dateline. While the future of other new series remains less certain, here's a look at how some of them are faring. MONICA RIZZO

LOSERS

TITANS*
Premise
A modern-day Dynasty, from TV megaproducer Aaron Spelling, starring Victoria Principal (Dallas), Perry King (Melrose Place), Casper Van Dien (Starship Troopers) and Yasmine Bleeth (Baywatch).
Pre-Debut Buzz
Money, greed, infidelity and beautiful people make this cheesy drama an irresistible guilty pleasure.
Status
It's a weak third in its time slot, behind Millionaire and the combo of Bette and Welcome to New York.
Prognosis
Not good, unless it moves. "It doesn't necessarily flow into The West Wing, an Emmy-winning drama that addresses serious topics," says TN Media analyst Stacey Lynn Koerner. "It's asking a lot of viewers to be in those two modes at the same time."
