If you think that this type of coverage glorifies an obvious psychopath - don't watch it.
If you want to understand what makes a person do terrible things - it won't explain that to you.
But, if you want to see how a (seemingly) average person managed to evade detection and escape police custody twice, all while leaving behind what should have been a massive trail of evidence - it's worth a watch.
Definitely not perfect, in particular I thought the exploitation of women's bodies was in very very poor taste. This isn't a vehicle to honor the many victims either, some are rushed over in what appears to be an attempt to accelerate the narrative.
The biggest question this leaves me with is - would we be better off removing all traces of evil people and the acts they commit? Neutering their legacy and wiping them from the history books. Of course, we can't do that with figures such as Hitler, Stalin, etc.... but can we and should we do that with serial killers, spree killers and their ilk?
We are always wanting to learn more about people who commit horrific acts; "what went wrong", etc... It might be hard to curb that instinct to know more. At least for me it is.
