SPOILERS AHEAD
Please, please, please watch this movie. It's so heartwarming and heartbreaking at the same time. Not everything is solved. Ladybird doesn't magically completely resolve her rocky relationship with her mother, in fact, her mother was so stubborn that she didn't bid Ladybird goodbye when she dropped her off at the airport to fly to New York for college. But after thinking for a while, she starts sobbing and runs to the airport, only for Ladybird to be gone already.
Their financial problems also drive conflicts between the tough love family, with the mother having her own conflicts and problems and hopes. Every character feels so real. The friendships, relationships, family problems, being a teenager. When Ladybird arrived in New York, she introduces herself to a stranger with her real name- Christina. It shows how she's starting fresh.
I sobbed so much during this movie, my eyes ached for an hour. It's a work of art.
