A cut above in terms of style, performance, and ideas, Todd Field’s film about a celebrity conductor accused of sexual misconduct is essential cinema.

Much like Lydia herself, Tar is a skilful, polished and fascinating piece of work, but it’s missing a beating heart.

The film is a genuine tragedy -- a black comic tragedy, but a tragedy nonetheless. When great artists betray their talent by treating it carelessly and abusing the power that comes with it, it’s always a tragedy.

Tár is ruthless and an exploiter. She’s also a great artist: no one will stop her working. That acknowledgement of the artist’s hunger and drive might be the most subversive, troubling and rousing aspect of this absorbing film.
