“Lady Bird”, the debut solo directorial effort from actress Greta Gerwig, has earned a perfect score on Rotten Tomatoes.

The coming-of-age drama starring Saoirse Ronan boasts an impressive 100 per cent “fresh” rating on the review aggregation website. Set in 2002, Ronan stars as Christine “Lady Bird” McPherson, a young woman living in California for a year. Lady Bird is an opinionated and strong-willed high schooler who navigates the relationships with her mother (Laurie Metcalf) as well as her best friend and teenage crush (Timothee Chalamet) while making plans for her future. Gerwig, 34, who also wrote the script, loosely-based the story on her own life.

The film, which arrived in select U.S. theatres on Friday, has racked up 82 positive reviews from critics, suggesting it may become an awards season contender. The film was one of the most buzzed-about titles at the Toronto International Film Festival in September.

Ronan’s performance could earn the 23-year-old Irish actress her third Oscar nomination – she was previously nominated for “Atonement” and “Brooklyn”.

“Lady Bird” is one of six movies to receive a perfect score on Rotten Tomatoes this year. Gerwig’s film joins “Faces Places”, “Jane”, “The Happiest Day in the Life of Olli Mäki”, “Truman”, and “Bright Lights”.  Jordan Peele’s directorial debut, “Get Out” earned a near-perfect score of 99 per cent earlier this year. Only 17 films have earned a perfect score in the past five years.

“Lady Bird” is set to hit Canadian theatres later this month.
