There were big swings at 10 PM on a otherwise pretty uneventful Wednesday night. After declining for 2 consecutive weeks and last Wednesday logging CBS' lowest-rated original telecast in the hour in 7 years last week, the network's new light legal drama The Defenders (2.5/7, 9.9 million viewers overall) bounced back, up 14% from last week among adults 18-49 and winning its time slot in the demo for the first time.
