Don't Worry, I'm Fine is a relatively simple film, but it soars thanks entirely to Melanie Laurent's revelatory performance. The film is about this young woman's struggle to go from being entirely dependent on others to learning how to rely on herself and be her own woman, and along the way Laurent goes through the darkest stages of depression and finds happiness. She keeps us with her the entire time, our heart hurting when her's does and our spirits lifting right with her. The kind of emotion that she digs into and pulls out is rare to see in film these days, but she is at the peak of the acting world. The way she emotes her struggle is wrenching and very empathetic. As a whole the film doesn't have a lot going for it, it sticks pretty close to it's one theme and goes with it, but at the end of the day it's a character piece that finds it's strength in Laurent's extraordinary work here.
