I am fascinated by true crime, had not heard of this doc until last night, stayed up late to binge the whole thing. It was very well done, shocking, emotional, horrifying, and even funny at moments because of the online sleuths.
This series is definitely not for everyone, I need to tell my mom to stay away. While they don't show the actual animal abuse, knowing what happened to those poor animals kept me up very late looking at the eyebleach subreddit.
