It’s not vile.
It doesn’t promote or glamorize drug use despite the claims. It’s like saying Othello promotes domestic abuse or Hamlet glamorizes violence.
The show has repeatedly showed the accurate and devastating effects of drugs and violence. The protagonist is doing a slow burn where he literally started off saying “no rough stuff” and now he doesn’t even blink when he watches a kid get shot in front of him. All because he wanted to help his family after he dies. The drug users are regularly shown to be foolish or low character. The only sympathetic bad guy on the show is Jesse (who is in constant torment because of his actions) and possibly Mike (who meets an unfortunate end). The criminal lawyer, his underlings, etc and all shown to be awful people. The only positively portrayed characters in the entire show are Walt’s son and Hank, both men who are always portrayed to be of the highest moral character. Hank even had a story arc where he was forced to shoot a drug dealer who pulled a gun, the result being grief over having to take a life. No glamorizing it or taking joy in it.
It’s a pretty good morality play done in 50+ acts.
The "good" DEA character is Gomez, who is clearly intended to be a foil: Hank as he should have been. And I'm betting Gomie is dead...
You don't think this is glamorous? Wendy Song!
