I read about this when the indictments were unsealed in 2017, read all the in depth pieces about "Superman", and the guys they robbed, watched first episode last night, it's impressive. A smart show, something of an insider show, that feels very adult, and intelligent, there's an offhand, blink and miss it, reference to Vanita Gupta, (Justice Department Civil Rights Division head under Obama Admin, and now reruned) which is just not something you see on many TV shows, from any streaming service.
As well as pretty much getting all the street material right, or accurate enough.
I prefer one season I think, and when the source material is true, shows can go off the rails after the writers have no more structure to base the plots on. After the indictments, the trials, maybe, there is just no more material. All the key players have been taken off the board.
