I enjoyed season 1 but not too fond of the changes in season 2. We don't need any of the manufactured drama amongst the gunsmiths, nor the manufactured drama between sis and brother. In season 1 I said they need to lose the sister, but for season 2 they are inserting her everywhere.
Also don't need all of the explosions. But with all that said, I still enjoy seeing the guns, learning some history, and watching them build guns.
