A young Englishman plots revenge against his mysterious, beautiful cousin, believing that she murdered his guardian. But his feelings become complicated as he finds himself falling under the beguiling spell of her charms.

There’s enough dark sizzle between leads Rachel Weisz and Sam Claflin to keep the audience involved through the underpowered middle stretches before the film regains its footing, delivering a disquieting shiver of a conclusion

Weisz shows her Oscar-winning talents by hitting precisely the right notes throughout My Cousin Rachel: from warmth to guile to chilly practicality.

It’s pure pleasure to watch Weisz as Rachel, who is also an actress of sorts, adapting to suit the needs and desires of whoever she’s seducing. Her manipulations feel more intuitive than conniving and need not be explicitly sexual per se.
