I'm an avid fan of true crime tv and have watched many different shows and documentaries on many different media outlets. Lethally Blonde is absolutely awful. I hesitated to watch this show, but watched to confirm my gut instinct. This show should be called, "Lethally Bleached Blonde."
The narrator, Holly Madison, is definitely not a crime analyst, expert, or journalist. As in The Playboy Murders, Ms. Madison (in fact, no one on the show) does not exhibit any sympathy and compassion for the victims of these very serious crimes. Madison and all her guests are flat and one sided. "Glamour" does not make an impact on true crime shows.
There is no real human emotion regarding the very real tragedy of murder victims and their friends and family. There are definitely much better true crime shows.
