I feel like just about everyone will connect with this movie in some way. It's funny, sad, charming and honest. Saoirse Ronan's performance is one of the best of the year. Her chemistry with Laurie Metcalf makes the Mother/Daughter relationship really work. Lucas Hedges and Tracy Letts are both fantastic too. I think every kid in high school should watch this movie.

Edit: I saw this again and it is still my favorite of the Oscar nominations. It really has a way to make you feel like your in high school again. Makes you realize how much you parents do for you and how much I love mine.

Edit 2: I watched this again, twice in two days, this time with my parents. My dad was cracking up at every time Lady Bird was shit talking her mom while my mom didn't think it was that funny. He also said some of the dad's lines literally right before he said them. After it ended my mom said "That's it? I thought she was going to come back and write her mom a check."
