Fuller House” season one was Netflix’s highest rated original-series season, according to Symphony Advanced Media. But new data from the ratings-measurement company suggests that the comedy’s second season was received with far less enthusiasm.

According to a ratings report released Thursday by Symphony, season two of Fuller House averaged a 2.01 rating among adults 18-49 in live-plus three ratings — measuring viewing within three days of the show’s Dec. 9 premiere. That’s down 62% from the 5.30 rating averaged by the show’s first season. The season-two premiere drew a 3.32 rating, down 67% from the season-two premiere’s 10.16 rating.

Symphony also reported that only 9% of the viewers that drove the season-one premiere’s live-plus-three rating returned to watch the season-two premiere. The report also asserted that the average rating for the entire 13-episode first season was inflated by high viewership for the premiere, and that there was significant drop-off from episode one, season one to episode two, season one. With percentage change from episode one, season one to episode two, season one similar to the percentage change from season one to season two, Symphony concluded that viewers who remained loyal to the show throughout season one have largely driven viewership for season two.

“Fuller House” is a continuation of the ’90s ABC series “Full House,” and stars Candace Cameron Bure, Jodie Sweetin, and Andrea Barber. It is executive produced by Jeff Franklin, Thomas L. Miller, and Robert L. Boyett and produced by Warner Horizon Television.

Netflix executives have claimed in the past that Symphony ratings for their shows are inaccurate, but have offered no numbers of their own to counter.
