Apparently the American public disagrees with you (that those shows are enough), since all of the shows combined don't bring in 1/10th the viewership of Sons of Guns (which, I understand, is why this TV show is being produced).
Personally, I don't watch much TV at all (outside of Hockey, Top Gear and Larry Vickers' program), so I'm not a good test case.
Whether you like those TV shows or not, you don't get a vote (nor do I) as to whether Gurney Productions is doing this TV show. They are.
That's the wonderful thing about America -- you aren't forced to watch anything.
