I feel María Isabel Páramo is not convincing

For me, María Isabel Páramo's work in Memories of My Father (2020) is easy to talk about after watching. The role needs more detail, but the performance stays on the surface. For me, it does not feel very real in many scenes. Many moments pass very fast, and I do not remember much after them. I do not hate it, but it did not pull me into the story. I remember both the good parts and the parts that did not work so well.
