This series is advertised as being a true cime story about the Golden State Killer.
Very quickly in the first episode, you feel like it's rather an advert for Michelle McNamarra's blog, podcast and book. The blog's URL is repeated multiple times like these bad adverts for car insurance and we're told by various people how great Michelle is and how great her book is going to be.
A lot of time is spent explaining how Michelle got interested in the case, how she investigated it, how she got access to evidence and sources, her thoughts and theories and how she wrote about it all.
Is this just a badly disguised tribute to Michelle from her family and friends?
If you stick with it, you do end up hearing from the victims and their story, and how the GSK operated but it does take a while.
The episodes though are often a jumble of bits which don't seem to have a particular order or flow to them. You don't feel like you are progressing through time or through an investigation. It's more like listening to someone remembering parts of Michelle's life story in random order until you reach the point when the crimes themselves are discussed. This makes it difficult to get into and at times quite boring.
Had they stuck to talking about the crimes, victims and investigations/evidence, it would have been a 2 (perhaps 3) episodes series but interesting throughout.
