Season 1 concluded — after just five episodes, shortened from the originally planned six-episode run — on July 2. The decision to cancel the series was made recently after a lack of clarity for both viewers and cast members about whether the series had the potential to continue. In an interview with Variety, star Moses Sumney said that he signed on thinking it was a limited series, while star Da’Vine Joy Randolph told Variety she thought “everyone’s intention [was] to have a second season.”
Overall, “The Idol” was poorly received, with a 19% approval rating on Rotten Tomatoes. Variety‘s review said that the series “plays like a sordid male fantasy.”
Ratings for the series were middling. It premiered with 913,000 viewers — 17% fewer than the 2019 launch of “Euphoria,” another HBO show hailing from Levinson that targeted a young adult audience, with fewer celebrity attached at the time of release. However, that number did grow to 3.6 million viewers after the episode’s first full week of availability, and now sits at 7 million. Episode 2 fell to 800,000 viewers on its first night.
Throughout the rest of the series’ run, HBO declined to share viewership data.
I never watched the show, but I saw this video on the first episode a few months back and it made me feel like I wasn't missing out on anything at all.
