Sennott’s mix of awkwardness, intensity, and smolder made her a revelation in Shiva Baby and another black comedy, Bottoms, and an almost-saving grace of HBO’s pop-star cult flop The Idol. She brings similar energy to the role of Maia, who aspires to a “big life” but has been languishing for years as an assistant at the confusingly named talent management firm Alyssa 180. We meet her on the morning of her 27th birthday, as she scrolls on her phone; has loud sex with her sweet teacher boyfriend, Dylan (Josh Hutcherson) during an earthquake; and then frets about her frequent UTIs from the toilet while he brushes his teeth. This is all very West Coast Lena Dunham. But despite its frankness, the show is more interested in ambition than in sexuality or gender relations.
