I guess I'll have to watch "Mindhunter" by myself since the wife saw the first 30 min and said it was too boring for her.
Mos Def see it. Without revealing anything, but saying a lot (so no spoilers, don't worry) it is a fascinating little genre experiment. You witness the very drawing of the blueprints for forensics in high profile cases. You see them go wrong and you see them go right about it, like tapping in the dark.
Genre experiment being in the fact that as it draws blueprints for the police procedure (in this case FBI procedure) it draws the blueprints for the procedural genre itself (TV series and movies).
Really good, but it doesn't try to entertain you. (Which I like)
