Netflix docs are very hit and miss but I rank Take Your Pills highly. If you're curious about both the historical and contemporary use of amphetamine both medically and recreationally, it keeps you interested and provides a balanced view.

On the other end of the spectrum I watched The Most Hated Man On The Internet recently and that was utter shit. It did not need three hour long episodes. Could have been done in 30 mins and summed up with "he bragged about shit under his real name and 4chan got him" lol.
