Well, look no further. "The First Wives Club," which opens Friday, is the latest and arguably the slickest chick flick to reduce its adult male characters to inconsequential quivery-lipped milksops. It's not so much male-bashing as all-out male-demolition, a happy-faced Hollywood excuse to trot out one vanillafied stereotype after another. Men are stupid! Men are venal! Men are libidinous reptiles!
