Why does this sound familair? Well, the reboot ws first announced in October 2019, but it did not have a network officially attached. Steaming services and other networks were in the running, but the series finally landed at peacock (A flightless bird, but also NBC's streaming service).
According to shadow and act, the genre of the series was mystery drama (making the OP think it might be like Nancy Drew on CW), but now seems to be a mystery-comedy (could still be like Nancy Drew on CW, I don't know I stopped watching after the second ep)
Variety reports: "The untitled comedy series is described a baby pink and bisexual blue-tinted, tiny sun-glasses wearing, oat milk latte and Adderall-fueled look at what happens when queen bee Cher disappears and her lifelong number two Dionne steps into Cher’s vacant Air Jordans. How does Dionne deal with the pressures of being the new most popular girl in school, while also unraveling the mystery of what happened to her best friend? - I don't understand, but that's what they said. Did Cher wear air jordans?
There is also a Clueless feature project in development at Paramount with Girls Trip writer Tracy Y. Oliver (girls trip) writing the script. No update on that project has come since 2018 - but, she has her hands in all of the pies right now.
What paperbag coloured, 3c/4a haired actress are you all fan casting for the role of Dionne?
