Teen drama an emotional rollercoaster

Lady Bird BBC2, Friday at 9pm ●●●● ●

Saoirse Ronan is in career-best form as teenager Christine, who endures a strained relationship with her mother.

There are laughs, but also heartache as helmer and writer Greta Gerwig treats us to a very impressive directorial debut.

Issues like failing family finances feel scarily relevant and there are no Hollywood rom-com-like conclusions to the romance.

Laurie Metcalf marvels as Christine’s mum Marion and Timothée Chalamet continues to prove he’s one of the finest young stars out there.
