Imagine the ratings a production of the Bible would get if Hollywood would adequately fund it and treat the subject with respect. This one is succeeding in spite of Hollywood and the networks.
I think he means succeeding at this, from TV by the Numbers:
HISTORY's 'The Bible' Week 3 Delivers 10.9 Million Viewers
HISTORY’S THE BIBLE WEEK 3
DELIVERS 10.9 MILLION TOTAL VIEWERS
#1 SHOW ON TELEVISION SUNDAY NIGHT
Cable Top 25: 'The Bible' Tops Cable Viewership for the Week
HISTORY Wins Week With Cable Primetime Adults 18-49 & With Primetime Total Viewers
I think you would have to call it succeeding. It sure isn't failing, despite the poor production values.
