That's an odd critique for perhaps the most well done expert film of the entire gangster action genre. That's certainly on the short list of the very best films.
I'd suggest you sit and rewatch it without distraction. It's a masterpiece.
@billt460 nails the response I would echo in post #53. I'll add some input.
First, this was filmed pre-wokism. Mann successfully showed a near unparalleled real look into this violent world, capturing incredible humanity and character development using very little screen time for each of many "major characters."
The black ex-con parolee. He was black, yes. Not unusual, considering disproportionate over-representation of black male felons, esp. in Los Angeles. Why is that unusual? He was also used to demonstrate a point about the abuse and racism in the system where his corrupt boss was taking a cut, which frustrated him right back into a life of crime. I bet that character only had 3 minutes of screen time. Yet you know a tremendous amount about him, and the actor did a stellar job.
I don't understand the critique about DeNiro's partner warning him from a pay phone. That would have been common in the era, b/c pay phones were anonymous and therefore essentially secure. This also set the stage for DeNiro to tap the black ex-con for the job, setting a course of action that got the black guy killed. "You in or out, let's go, right now." We see his wife, for maybe 1 minute of air time. But we know the entire back story and her pain from the discussion of how proud she was of him, only to see he died in a bank heist on the news... Her 1 minute of screen time, tells a lifetime of powerful backstory in expert fashion.
Waingro's violent streak was used repeatedly to illustrate a point about his violence and unpredictability, and mental instability. He needlessly murdered the guard, which forced the crew to kill the survivors and caused a major side story, which was the cat and mouse between the crew and Waingro, hired to try to get the crew while they were trying to get him. We see that he tortured and murdered the Hispanic guy and his wife. Mann really punched it home with just how violent he was, and the hooker scene showed his derangement. I'm not understanding the critique on showing just how demented violent he was in killing the hooker. Oh, and this connected Pacino's character to the bad guys, b/c if you remember Vince had to show up for the homicide. We got to see the violence of street life, and the real character and humanity between Vince and the dead girls mom.
Then you have Val Kilmer's character and Ashley Judd. Yes, he has a violent temper, and is abusive. It's not a one way street, as Judd blew all his money and was carrying on an affair. It was a mutually abusive relationship, which probably represents at least a large majority of marital situations. The interactions with DeNiro and Judd when he catches her, and later her moral dilemmas with turning in Kilmer, but then ultimately protecting him from the police trap, are all exceptionally well written and acted, showing her struggling with her own moral dilemmas. I cannot fathom a critique on these relationships as so expertly and realistically portrayed.
DeNiro knows Pacino is generically on to him and following him. It's a cat and mouse. They "warn" each other. Pacino wasn't telling DeNiro anything he didn't already know, that yeah they are following his moves. DeNiro then expertly dumps the tail, and disappears. DeNiro and his crew got plans for a bank. Pacino did not know which one. Did you also see the scene where DeNiro lured Pacino's crew out into the open to get pictures of Pacino's crew?
Rewatch the film. You missed a lot and seem to not really understand it.
This whole ecosystem and interactions were exceptionally well done with many important side stories, which is alarmingly lacking in modern "paint by the numbers" movies. In Heat, there are probably 10 important side stories.
* Vince's job stress has destroyed his marriage, and his daughter is psychotic from neglect.
* DeNiro is lonely, and just wants one more score to disappear.
* Kilmer has conflicts with the job, his neglectful cheating wife, his temper, etc.
* Waingro is in a cat and mouse game, both chasing and being chased by DeNiro's crew. He's hired by Van Zant who is trying to double cross DeNiro's crew. DeNiro's crew wants revenge on Waingro for his bad behavior.
* Corrupt banker guy Van Zant that had the bonds stolen, and his attempts to double cross DeNiro and DeNiro's motivations to get him.
* Black ex-con and his wife and their side story.
* Dead hooker, her mom's pain, that street life, Vince's engagement with that as it connects Waingro's behavior, which also shows how terrible his job is.
* Trijo, his motivations and ultimate demise with his wife, and mutual loyalty of DeNiro.
* Motivations, thrill, and loyalty of DeNiro's crew, particularly Tom Sizemore.
* Voght's character, who acts as a fence and gathers information, gets fake IDs, etc. is obviously well connected, etc.
* The gang's doctor/surgeon, played so well by Jeremy Piven. Probably 1 minute of screen time, but impressive character development.
* Vince's character, dealing with the underground, and ignoring their crimes (car thefts, dog fighting) to get information on major crimes (this highlights the dirty morally hard work of this career), and meeting with actor/rapper Tone Loc in a great short role.
* Natalie Portman expertly plays the young troubled daughter, in a role of a kid with abusive drug addicted cheating or neglectful parents.
* Vince's wife, who struggles with addiction and is cheating b/c she feels neglected, not understanding the stress of Vince's job. Just some pampered bored housewife, a terrible parent, addicted to pills and cheating...
On top of this, we are treated to among the best heist and action scenes on cinema. The very creative bank truck heist, ramming it with a stolen tow truck to flip it and disorient the guards with a crash and a bomb. Several excellent gun fights, including the creative one across the runway at the end. And of course, the major bank heist scene. It's a total masterpiece.
It's a miracle to fit all of that in so expertly well with a short run time of under 3 hours.
