I binged Netflix's 3 part special "Killer Inside: The Mind of Aaron Hernandez," Oxygen's 2 part special "Aaron Hernandez Uncovered, and Investigation Discovery's 2 part special "Aaron Hernandez An ID Murder Mystery."
Both are amazing and filled in so many gaps. Watch the Oxygen special first then the Netflix and ID specials because they fill in gaps for each other.
Together they are 5 stars out of 5. Separately I would say the Oxygen special is a high overview, the ID is more about the case, and the Netflix special is a deep dive. They all EXPLAIN Aaron's behavior, but don't EXCUSE him.
I hope these specials help others before they go too far as well.
