Beyoncé‘s HBO documentary Life Is But A Dream may have garnered mixed reviews, but it pulled in record ratings for HBO.

The superstar’s documentary had the “largest audience for a HBO doc since Nielsen revised its method of measuring viewership in 2004,” according to The Hollywood Reporter.

Beyoncé’s documentary premiere drew 1.8 million viewers, breaking the previous record of 1.7 million set by Spike Lee’s Hurricane Katrina opus When the Levees Broke: A Requiem in Four Acts in 2006.
