I agree with other posts - it's by far been my favorite hunting show to watch out of anything that's ever been filmed.
One of the things that I like the most about the show is his discussion of the deeper thought processes behind just "we're going to sit in this box blind and hopefully shoot a big one...here goes!" It's not that those types of shows are bad, they just don't add any richness to the experience. I've sat in a box blind and shot a deer - it was fine, but it doesn't get me fired up about the whole experience. He talks about the history of the area, the difficulty of the pursuit, what it means to take an animal, why understanding where your food comes from is important, and so many other topics. On top of all that, he communicates in a way that is engaging, educational, intelligent, humble, and sometimes even profound. He even makes a point to discuss the importance of mentoring others, and dedicates a good bit of screen time to taking less experienced hunters on their first trips and walking through the process of hunting and food preparation.
Some hunting shows are about a person showing off their hunting success in the best possible light. His hunting shows are about hunting as it should be - a personal pursuit that's centered around connecting to the natural world, the past, and the food we like to enjoy.
I like that he puts himself in situations where he's not the expert, and is willing to show others those situations and admit "I'm no expert, but look at how awesome THIS person is". The grouse hunting episode in Alaska was a great example of that.
