So-So Return For NBC’s ‘Marriage Ref’

NBC’s The Marriage Ref returned to lower ratings last night, albeit on a slow Sunday where it still ranked as the No. 2 program of the night. Ref averaged a 1.6 adults 18-49 rating in its second-season premiere, well down from a 4.9 for its premiere in March 2010, when it debuted behind the closing ceremonies of the Winter Olympics.
