I dont know if it was Charles S Duttons decision to do the rapid time jumps to the past during a scene then come right back, but its genius. In episode 3 and the mothers gonna go into rehab, what a bleakness. I remember watching an actual documentary of black tar heroin on HBO once, and they followed 3-4 hardcore junkies around for one year. Truly horrifying, worse than what Ive seen so far on The Corner even.
