Ted Mills’s review published on Letterboxd :
The first half of this film, a social satire about mental illness crashing into the self-involved world of social media (esp. Instagram, and the worlds we construct therein) is so spot-on that the second half, where the plot chugs in unannounced, can only disappoint. Aubrey Plaza has this character, Ingrid, down perfectly, as we spend most of the film wondering if we should laugh with or at her as she inveigles her way into the world of a Instagram marketer/shallow twee person played by Elizabeth Olsen. Nobody seems to have an actual job; avocado toast is eaten; there's vaping (O'Shea Jackson, the voice of reason in this film); and all the locations you expect to see (or be referenced) in Joshua Tree are there. As I said, spot on.
It almost craps out near the end too, but the final scene saves it and shows that Matt Spicer knows what he's doing in his first feature.
