I feel Keesha Sharp is not convincing

Keesha Sharp as Capt. Celeste Rhoades in Titanic 666 (2022) made me pay attention more than I expected. 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. 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. I remember both the good parts and the parts that did not work so well.
