Extremely devastating, brutal, uncomfortable, and so well done. This movie is absolutely insane and doesn't hold back for a second. Addiction is depicted about as perfectly as it could be, horrible and terrifying. It slowly builds up without you realizing it, because it already starts uncomfortably. Something is already off, and then the movie continues to throw you in even more. Again, it's so well done. I recommend it, for sure, but it is hard to stomach, especially towards the end. You just understand and feel bad for every character involved, and it paints an excellent understanding of the reality of addiction. People aren't addicts cause it's a choice, they're addicts because it's a dependency. One of the most intensely depressing and wild movies I've ever scene, as an immense compliment.
