VIDEO : Walking Dead Midseason Finale Hits New Low

The Walking Dead is still a tough act to follow, but it's definitely trailing its own heyday. Sunday's midseason finale, while avoiding another season low, brought in 25 percent fewer viewers than the comparable episode last fall. The most recent live score is still up a shade from the previous week's season low, which marked The Walking Dead's smallest audience in six seasons, but it's one of the clearest signs yet that the show is on the downturn. The good news ? and there is still quite a bit of it ? is that the series still ranked No. 2 for Sunday night, trailing only NBC's Sunday Night Football.
