The film was widely praised by critics and received a score of 99% on Rotten Tomatoes’ ‘tomatometer’ in a record-breaking streak of positive reviews on the website. The previous record having been set by Toy Story 2 in 1999.

Elsewhere reviewer Susan Wloszczyna on wrote that, “The opening moments of “Lady Bird” accomplish so much so quickly, it takes your breath away.”

Speaking afterward Ronan said she thought the reason the film was so popular was that, unlike so many films, Lady Bird doesn’t need a man to feel good about herself.

“I think the reason why women have related to Ladybird, and girls and women have really taken it as their own story, is because the main character isn’t validated by a boy,” Ronan said.

“A lot of times in coming of age films that’s the one goal and focus. There has been such a massive conversation about [women in the film industry] and I hope that because so many of the people are well-known, it will cross into other industries too.”
