Well I watched the 'Unbraided' episode and the S3 first episode 'Mars on Earth'. Enjoyed them both. Although I like and miss Dave, I think Joe will do just fine with Cody. They're both alpha males and somewhat set in their ways, but the contrast in styles makes it interesting and give you some different perspectives and options to consider.
Yes, it is a show. Yes, situations are somewhat set up for them. But I have learned some things from S1 and S2 and more than that, it helped motivate me to do further research and seek ways to be more self-reliant.
Looking forward to the next episode.
