I feel Chloe Campion is not convincing

I watched Look at Me: XXXTENTACION (2022) and Chloe Campion was one of the parts I kept noticing. I do not hate it, but it did not pull me into the story. Some emotions are too simple, and I cannot believe the character enough. Many moments pass very fast, and I do not remember much after them. The role needs more detail, but the performance stays on the surface. This is only my personal view, but the performance changed how I enjoyed the film.
