Despite widespread critical flak over the talent -- or lack thereof -- of the principal male contestants on Fox's American Idol, Tuesday night's show continued to draw blockbuster ratings. Its 16.4 rating and 25 share was greater than the ratings of the other three major networks combined. So was the 15.2/23 for House, which followed Idol. Nevertheless, the numbers for Idol fell below those for the previous two weeks, when they averaged a 17.2/26.
