I feel Sıla Karaca is not convincing

For me, Sıla Karaca's work in Flashdrive (2020) is easy to talk about after watching. For me, it does not feel very real in many scenes. I do not hate it, but it did not pull me into the story. The role needs more detail, but the performance stays on the surface. Some emotions are too simple, and I cannot believe the character enough. This is only my personal view, but the performance changed how I enjoyed the film.
