Like Sly, Rambo is not young and war is a young man’s game that he will still have to wage to rescue his friend’s daughter in the film.
The old soldier going in to battle one last time has something of an Old Man Logan/Unforgiven vibe to it.
Still though, in a way it adds a layer of realism to Last Blood.
Given the damage he says he took on Rambo 5: Last Blood, it’s probably a good thing that Sylvester Stallone is closing the chapter on this character as well as his time as Rocky Balboa.
