Monday night was the official start to the 2018-19 TV season, and NBC emerged victorious with “The Voice” and its series debut of “Manifest.” CBS finished primetime as the ratings runner-up, despite “The Big Bang Theory” dropping hard from last season’s huge premiere, which was boosted by a Sheldon and Amy wedding-proposal cliffhanger.
