Both actors contribute knife-sharp timing and the kind of intensity needed to make this essentially two-man setup work.

It's subtle, and may not be enough for the growing group of critics and viewers that worry that the cinematic obsession with serial killers ends up lionizing them, but it makes Bundy what he always was: pathetic.

Interesting. It's not bloody, it's not gory... It's about this process that this profile went through.

It never feels like he's taken to task, but in a way Sealey is exploring the darker aspects of mankind, and the film, much like most people in his orbit, is seduced by Bundy's mannered, and often witty conversations.
