I understand why some people wouldn't like it. I think we're saying the same thing, but from a slightly different angle. It's the fact that we're not supposed to like it, but we're forced to endure it, rather than have it censored for us, like westerns in the '50s where a bullet magically kills a gunfighter without even making a hole in his shirt.
I would argue that SPR's intentions were set higher than the average action-war flick.
The Chinese take on SPR (Assembly, set during the Civil War between Nationalists and Communists) was probably even more graphic and horrific, yet it was a moving film, focusing on human emotions and suffering. The graphic nature of the violence becomes part of the story-telling, and off-sets any feelings of jingoism in killing, that you might gain from a Rambo movie.
It is my opinion that you are being misguided by the hype.
