It's well compiled. The narration got me invested. Shot beautifully, the suspenseful music is excellent. The movie as a whole is...yeah it's fine? It lacks depth and some scenes lack logic as well. It makes for a fun watch nevertheless. Better than most of the stuff going around these days. A one time watch and you never think about it again kind of a watch. Not Fincher's best but not his worst either. Fassbender is decent in his role portrayed as a mysterious killer who has a knack for everything pretty much. Solid punches to the face by a guy twice his size does not faze him at all. That's about it really.
