If you're like us, you're weary of local TV newscasts that somehow manage to be simultaneously stuffy and shallow. It's not like that with KTVK's NewShow, an informal yet informative experiment in local journalism and, yes, infotainment. This hourlong 10 p.m. newscast is led by real news, and then -- much like the progression of sections in a newspaper -- gets softer as the minutes fly by. Channel 3 is still the most fearlessly directed local broadcast operation, capable of grinding sacred cows into red meat. But it's the laid-back, whimsical sense of the NewShow that's most refreshing. It's a risky format, and we admire the chutzpah. The irrepressible Liz Habib, who's more hostess than anchor, sets the tone. She's a chameleonlike pro, able to convey empathy when she's reading the grave news yet maintaining a beguiling and impish mien when the show lightens up. The likable yet credible Mike Warren is Habib's trusty sidekick. The NewShow'sexploration of Valley nightlife, music and alternative culture is a sensation with a younger demographic (dare we call it "alternative TV"?). Mike Chamberlin, meanwhile, is a sportscaster with conviction. He's not afraid to call a shovel a shovel, or tweak the barons of the Valley sports scene when the situation warrants. Sure, we'd like to see more investigative and enterprise stories on the NewShow -- the hourlong format pleads for it -- but the show is still in relative nascence. So we'll give the Channel 3 crew until the next Best of Phoenixto serve even more nutritious fare.
