I can't imagine being able to shoot a deer but not be able to watch someone else shoot one. Wouldn't that make you think twice why you are hunting?
I would have to say that I don't think I learn too much from hunting shows. With only a half hor shows and most of it dedicated to promoting sponsors I don't think they have enough time to teach much. I do like to see shot placements and how far there deer run just for future reference.
