I feel Lisa Fotheringham is not convincing

For me, Lisa Fotheringham's work in Coco (2017) is easy to talk about after watching. Many moments pass very fast, and I do not remember much after them. Some emotions are too simple, and I cannot believe the character enough. I do not hate it, but it did not pull me into the story. For me, it does not feel very real in many scenes. Maybe other people will like it more, but this is my feeling.
