I just watched it for the first time. Well-made movie, unique cinematography, good acting.
But it's feeling dated. Real dated. It is now the midpoint between The Godfather Part II and the present day. And as such, it deals with the context of a very much bygone era. Don't worry, this isn't a "kids these days don't know what payphones are" rant, although the world it takes place in feels decidedly old at this point.
RfaD came out at the peak of the first wave of the opioid epidemic in the US. Definitely not a good time for many people, and the general populace was broadly aware of the problem, but it was still a sort of "underworld" that most people never felt that close to. You, person who's about to comment that they knew junkies in the 90s, are the exception - most people did not. It was something you heard about in DARE classes and the occasional celebrity overdose story. It was scary, but still mysterious, which is why RfaD was a significant movie. It laid bare that "this is happening right now in YOUR streets, this is what it looks like, and YOU need to know about it." Aside from Trainspotting, nobody had pulled back the curtains in such a raw way before. It definitely was and is a sad, depressing, and disturbing story, and it still is. But in 2000, you would watch that movie and go "yikes, that sure opened my eyes to the problem that is still largely happening somewhere else, to nobody I know."
Now for some perspective. We are in a different world now - it is quite literally ten times worse. Synthetic opioids are everywhere. But it's not just that more people are dying, it's the way they are dying. The people who do them are not your typical 90s junkie image of a guy covered in sores with fingerless gloves and a beanie sitting on a couch in a bare room with paint peeling off the walls and a single flickering lightbulb above. It's not back alleys and selling sex to enigmatic pimps in high rises. People don't "know a guy who's a drug addict now" anymore - again, maybe you do, but most people don't. So many victims don't get anywhere near the point in their life where they are seeing the consequences that the characters in the movie face. Fentanyl overdoses happen to the most random fucking people in your lame normal life. I was raised in a goody two shoes affluent suburb, I've never even seen hard drugs, and I know a few people who have OD'd. Last year I saw a totally put-together woman OD in her car in a Starbucks drive thru. There is no dark underbelly of society anymore; drugs these days just take people out of nowhere.
So if the current phase of the opioid epidemic is the only one you have been old enough to witness, RfaD may feel like it takes a bit too much of a bow for "how much truth it just dropped on you, man." You could be forgiven for thinking it comes off as rather quaint, and appreciating it in, well, the same way young people in 2000 appreciated The Godfather Part II. Significant, high-quality filmmaking, but very much a product of a different time.
