That was a good exegesis of the film's themes, I think it gets a lot right, although it's been a while since I viewed
this morning i was thinking about something i tried to articulate there with regards to eastwood's standing with the Hmong vs his own family, and how much of a stranger he becomes with them vs the acclimation he gains with the Hmong.... its a common distancing of the old guard to their new generations.... eastwood, as a korean war vet was promised an american dream, that would be his reward for being ordered to kill, but decades later, that dream has been eroded, he chastises his son for not driving american, but this is more of a symbol of how his son has leveled up eastwood, the Gran Torino is a prized relic, but it is prized because of how dated it has become, and thus how dated eastwood is, and the false dream he was sold.... his son lives a new american dream, he has a wife and two children, he lives in a suburban house, driving a toyota, japan not the same as korea, but asian nonetheless, which is who eastwood fought against.... the world eastwood himself lives in is the once american auto driven economy of Detroit, that is depicted as a desolate and stale average suburban area that may look no different than any city not named New York, Chicago, Boston, or LA.... a city also that is filled with minorites, "spooks" and "zipperheads", those eastwood had, in his past life, fought to protect america from, but now in this life he is forced to live with them, and acclimate with them, and then by the end of the film, the Hmong son, is shown to be even more of a son than Eastwood's real children, given that the Hmong were given the titular Gran Torino.....
The film is also interesting to view as a Neo Western, and to view in light of Eastwood as an american cinematic icon.... especially with his death scene, which is essentially, for lack of better terms, assisted suicide, or suicide by gangster, where as when we think of Eastwood as a hollywood figure head, we see the Man with No Name gunning down anyone who stands in front of him, or Dirty Harry bringing justice to criminals in any way he deems necessary.... but we're far gone now from the wild west, or the 70s and 80s streets of San Fran, this is a new turf war, he no longer has a magically quick fire from the holster, or a badge and a gun that can put anyone in their grave, the only way he knows he can stop these new gangsters and end this turf war is the ending of his own life
