I went into Eileen knowing absolutely nothing, and that’s exactly how you should approach this intense little indie.

Lured in by the cast chalk-full of actors I enjoy, Thomasin McKenzie as the marquee name seemed a unique opportunity for me to see her showcase her talents.

While she has a handful of credits — Last Night In Soho, Old, Jojo Rabbit — she’s never been the main reason I’ve seen a film. After seeing her here, I will personally seek out every credit on her resume.

She stars as our title character, a quiet, shy young woman who works at a prison facility. Eileen has a difficult life, spent taking care of her alcoholic father, a retired policeman who can barely manage his own traumas, but thinks he knows what’s best for her.

Alienated from her co-workers, she goes about her day-to-day job with little for comfort and solace. But when a new doctor starts at the prison, she soon forms a quick, unhealthy bond with the older, alluring Rebecca.

To say any more would change your experience of the film — Don’t spoil it for yourself. Skip a trailer or a review (other than this one, of course) and just see it for yourself.

With McKenzie giving a career-best turn, as well as Shea Whigham, Anne Hathaway, Sam Nivola, and Owen Teague at the top of their game, you won’t be disappointed.

Director William Oldroyd makes an affecting, alluring feature that will stick with you, especially if you take my advice and go in with a blank slate.
