The new Aaron Hernandez documentary is making it near impossible for the family of Odin Lloyd -- the ex-NFL star's murder victim -- to recover because they were blindsided by the film.
Sources close to Lloyd's immediate fam tell TMZ ... they feel like old wounds were reopened this past week when Netflix dropped "Killer Inside: The Mind of Aaron Hernandez" ... which chronicled Aaron's life and murder case, starting in 2013.
We're told they largely tried to move on after Aaron was convicted, but now they feel the doc is dragging them back into a dark place and forcing them to relive painful memories.
