I didn’t click to Lady Bird’s tune. It seemed to me to be oversimplifying a period in a person’s life which is supposed to be filled with issues at the same time flimsy and yet intensely complex. The “What now?” question has a lot of depth, especially as it’s put on the shoulders of an 18 year old. Think only of the subtextual meanings wandering in the 1967 Graduate.
Still, probably Gerwig wanted to do something that feels close to what she felt during that period and there’s nothing wrong with that. It’s in the balance of the served morals that I lost interest, the “my name is Christine” moment towards the end, which I can bet 5 bucks that the director regrets post-factum. It’s not the end of the world, neither the beginning of a new one.
