Brandon Williams’s review published on Letterboxd:
😞 Cannot believe I didn't like this. Didn't live up to the fantasy of the cover. Ultra weird story. I'm sure there are some metaphors behind it, but didn't really pick up on any of them. Should not be tagged romance. I love musicals, but usually don't vibe when they put straight dialog to melody. Driver was "sing talking" way too much. Also too few actual musical numbers. A lot of weird junk.
Your mileage may vary, but half way through I was really losing interest. Not enough Marion Cotillard. I say skip it.
