Definitely a suspense. And I feel like If you don’t have the attention span to sit through plot development of a movie that is a suspense not a guns blazing explosions going type of movie this ain’t for you. But this is a perfect step into the mind of those who have been detectives and worked on investigations and the toll it can take on their family life, themselves, and their overall mental health. Psychological suspense thriller and it does just that. No extra bs it was pure and I loved it
