People are calling this movie racist. No, you don't get it do you. You didn't live in those times did you? All you newbies to this movie think in terms of the 2016-2020 mentality.
There were bad cops then, just like now. There was racism and there were severe gang problems in the inner cities. Cops were overzealous, and gang members were bad asses that didn't really care about whose life they took.
It reflects the times. The movie isn't racist. It's a reflection of what was going on then. If you didn't live through the 70's, 80's, 90's and then into the 2000's, and you're commenting on how racist this movie is, you have no idea about what life was like back then, seeing it through a 2019/2020 lens.
Is it poorly acted? Maybe in parts. Is it the greatest movie of all time? No, certainly not. But it works, and it's a good picture, and it's a social statement, that's what it was meant to be.
It's not like we've eradicated crime and gang violence. But back then, it was a lot to deal with, and this movie depicts it well.
It is actually one of my "must watch" movies for anyone who hasn't seen it, to get acquainted with some history of gang violence, and the policing of the 80s and 90s.
