Shanna Besson did not work for me

I watched Taken 2 (2012) and Shanna Besson was one of the parts I kept noticing. 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. The role needs more detail, but the performance stays on the surface. 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.
