I'm on season 3 and it is fascinating to watch its almost a serial killer pouncing on a victim after a victim. It is mesmerizing when they say the trapline stretches 100 miles or 200 miles etc. Scooping up dead lynx after lynx. A trapped lynx or marten is not just one dead but they could have babies in burrow near by and they wiped out the entire family. They do a good job justifying what they do, in their own mind in the name of freedom, needing to survive, carrying on the tradition etc.
On to the season 4. Now it is a pain in the bone to watch; a husband wife team embracing at each kill, laughing and highfiving. You wonder how good is living.
