Me and the wife watched most of it the first or second week of lockdown it was really good but such a hard watch it took us ages to get around to the final episode which was as you say so harrowing we couldn't believe we lived in a world where something like that could happen as recent as it did. Then a few days later the murder of George Floyd happened and that really highlighted our white ignorance. Obviously we weren't oblivious to racism just the sheer extent of it.
I've had a shit and hard life losing my parents before i was 30, past abusive relationships, depression, anxiety, alcohol abuse, bullying and hospitalisation during secondary school. But if live that life a million times over than 1 life in the shoes of any black man woman or child and what they've put up with for so long.
