The storyline is okay. Interesting that they made this story go from one era to another. Another serial killer drama. You can't even say these types of stories are nonfiction. You surely don't have to go through one era to another to know there are psychos out there. The United States has its own history of this horrific crime. The cast did bring this story to life to the screen, it will keep your focus. The visuals and actions were great. This is the type of drama if you go through a tunnel, you don't know what's at the other end.
