The latter two Rambo films, Last Blood included, have also gone hard on the visceral violence.
First Blood Part II actually has Rambo basically go back and refight the Vietnam War (and win).
First Blood, saw Sylvester Stallone in a film that, while it wasn’t light on action, was much more focused on the character drama of a man suffering from PTSD.
I can only imagine how bloody the Extended Cut of Last Blood is considering the theatrical cut was not shy in that regard.
