It's pretty simple, if you choose to go graphic in a horrorfilm you gonna have a lot of blood. When you think about the Alien chestburster scene it clearly doesn't have enough blood to be realistic. It doesn't take anything away from that scene though, still and forever classic.
I really don't understand the worries. You're gonna get what you all wanted for decades. But this time it's probably more graphic because you know movie technology is better now so you can show more.
It should be intense and from what we heard today it is intense.
