On this week’s show, the hosts are joined by a very special fourth panelist: Wesley Morris, a critic at The New York Times and the host of The Wonder of Stevie, a new podcast on Audible. First, the quartet explores The Substance, a lurid, monstrous body horror flick by writer-director Coralie Fargeat. Demi Moore stars as Elisabeth Sparkle, a fading Hollywood icon who is so repulsed by the idea of aging, that she purchase a black-market drug known as “the substance.”‌ The film caused a commotion at Cannes this year, where audience members reportedly walked out in disgust and the remaining crowd gave it a 13-minute standing ovation. Then, the panel dives into The Wonder of Stevie with its host. The new six-part Audible series explores the career of Stevie Wonder and “uncovers the untold story of an extraordinary artistic journey that shaped the greatest creative era in popular music history.”‌ On the show, Wesley is joined by guests including Barack and Michelle Obama, Questlove, Smokey Robinson, and more. Finally, the hosts discuss A.I. slop and the onslaught of online garbage and language model detritus. This conversation was inspired by Max Read’s piece for New York Magazine, “Drowning in Slop.”‌ In the exclusive Slate Plus segment, Wesley Morris sticks around for a classic Slate spoiler special, and joins the hosts in dissecting The Substance and the film’s controversial, bloody, and borderline nauseating third act.  Email us at culturefest@slate.com.  Endorsements: Dana: Stevie Wonder and Gilbert Gil performing live in Brazil in 1995.
