SEASON FINALE: Last season, this series ended with a cliffhanger so dramatic, especially for a comedy, that it took me by surprise. Tonight’s season ender has its surprises, too – and its twists, including the jealous announcement by Carol (Kathleen Rose Perkins), the mistress of John Pankow’s TV executive Merc, that Merc’s blind wife is having an affair – with Matt LeBlanc, the star of one of Merc’s shows. We viewers have known that all along, but watch what happens when Merc finds out.
