"Right now, give [Kate] Winslet your undivided attention."
— Barry Hertz, Globe and Mail
"One of the finest films of the year: a shiveringly passionate period piece."
— Robbie Collin, The Telegraph
"Francis Lee's forbidden-love story in 1840s England is vital and austere, not unlike the fossilized sea creature that gives the film its title and poignant symbol."
— Peter Howell, Toronto Star
"Ammonite will make you feel as if you’re right there in Lyme with Mary, sharing her loneliness and delighting in the small moments of joy she allows herself, all the while breathing in the crisp sea air."
— Orla Smith, The Film Stage
"One of Lee’s brilliant choices is to refuse to put a soppy romantic gloss on the affair. He suggests instead that passion can blind lovers to a true understanding of each other as easily as it can open their eyes."
— Caryn James, BBC
"'Ammonite' is a passionate love story nourished by the salty sea air and the blissful absence of men; it's also a sharp reflection on how the artistic, scientific and intellectual contributions of women have been systematically written out of history."
— Justin Chang, Los Angeles Times
"This is the work of a mature filmmaker in full command of his voice, yielding remarkable performances, chief among them a complex character study of stoicism and desire from Kate Winslet that might be the best work of her career.
In many ways it's a deceptively modest work, but Ammonite just floored me; I can't think of a single aspect that could be improved upon."
— David Rooney, The Hollywood Reporter
