Jaime Rebanal’s review published on Letterboxd:
Works in many ways as a perfect female counterpart to Francis Lee's debut film God's Own Country, though it doesn't quite gush out the romance immediately in the same way that the aforementioned film had done so. It seems to work against the film's own favour, because the romance doesn't immediately hit but there's also something that I'm still drawn to in how Francis Lee lets everything develop, within the feeling of comfort that Kate Winslet and Saoirse Ronan find within the presence of one another.
Nevertheless, there was still something about Ammonite that I found to be otherwise lacking. In crafting a love story between two different kinds of people, both that their respective actors best capture, something about the structure still never clicked as well with me as I feel like it should have - and by the time the film came to its end, it seemed too little too late. Not that this was a deal-breaker for me, but as it stands, I still have my own reservations.
Also, I'm not going to bother pitting this against Carol or Portrait of a Lady on Fire for as inevitable as those comparisons may be.
