Kona Gallagher of Cinema Blend said the premise was interesting and that "[Valley Girls] has the potential to be a strong spinoff, and [she] hope[s] that CW decides to pick it up this fall." Dave Itzkoff of The New York Times writes that he "especially liked the moxie of Brittany Snow as young Lily and Krysten Ritter ... as her sister, Carol. And of course the retro soundtrack was a total trip." A few review sites took issue with the episode's script, such as BuddyTV, which claimed it was cliché, and Television Without Pity, which found it repetitive. While writing for The Frisky, Sara Benincasa praised the clothing styles and called the overall episode "awesome fun!
