Billie Piper’s feature debut as writer-director is a peculiar “anti-romcom” – a post-Fleabag-era tale of dysfunctional male/female relationships, tinged with musical fantasia and built around bitterly comedic theatrical dialogue. Boosted by an exceptional cast, and sharing an edgy energy with Piper’s recent TV hit I Hate Suzie, it’s an ambitious, nervy work that occasionally trips over its own stylistic heels, but still proves, as Buzz Lightyear famously discovered, that flying is essentially falling with style.
