NBC, it would seem, just can't catch a break. Although its new comedy Bent received decent reviews, it was watched by just 2.57 million viewers on Wednesday. Among the key 18-49 age group, it drew the lowest ratings for any in-season comedy premiere ever. The result was fuel for headline punsters' pens. " Bent Out of Shape," said AdWeek. " Bent Premiere Falls Flat," headlined Broadcasting & Cable magazine. "NBC's Bent Broken in Bow Wednesday," said Daily Variety . NBC had to contend with another major flop Wednesday. Rock Center with Brian Williams was watched by just 3.02 million viewers, about a third as many who watch him on NBC Nightly News . Over on cable's Fox News Channel, Bill O'Reilly drew more viewers -- 3.10 million.
