There is only one thing I have to say: YES. YES. YES!!!!!
If Lady Bird was a person, you would be able to relate with her, you would think she was funny and wise, and you would think how graceful she is. After watching this movie, I could not stop thinking about it. The premise might seem shallow, but it is very deep. It chronicles everyday teenager troubles and first loves and parent problems, but without being pretentious and tedious. Great actors, amazing directors, and professional screenplay. Definite recommend, but not for children under 13, since it has adult themes in it (i.e. cursing, sex).
