I was also getting frustrated with how they acted like little retards trying to save Finn instead of having peace with the grounders. Good riddance, I didn't like Finn that much anyways.
This show is alright but I'm having trouble understanding where all the goddamn cities are... civilized cities didn't just vanish into thin air, and didn't get eaten by the ground, so where the hell are all the buildings and stuff? Season and a half and still all we've seen is a bunch of forests and the statue of Lincoln.
