For me it's Saw series, Rambo is not that much full of gore to me, I do say that Saw is! And Rambo doesn't even disturb me mind when I watch it, but Saw does! So, for me, it's the Saw Series! Saw owns Rambo! I think? Lol. :P
I didn't see saw...but rambo was frikin gruesome. I was really suprised, of course a lot of rambo's gore was a bunch of bs, like the sniper shots that knocked those guys like 20ft back,lol. Or that .50cal machine gun totally cutting ppl in half......maybe in like a stream of shots to one person, but not one bullet...soo Rambo's gore wasn't really that bad cuz its so fake.
