BTW, something they also don't get right is that you can smell fresh blood, and it's quite distinctive.

Quite a number of novels I've read do mention the smell, usually calling it "metallic" or "coppery."

I suspect the reason that movies and TV shows don't do the same is that the medium is primarily visual and secondarily auditory, with the other senses referenced only implicitly. A wrinkled nose and/or a hand over the mouth is about the best you can hope for in regard to smells. Maybe that will change when virtual reality really gets going.
