I was not impressed as well, both with the production and the way Ms. Kim came off.  
Still, bottom line IMO is that the Kim's were not stupid or negligent..........

I've driven a small portion of that road, closer to Merlin, on a sunny August evening. I can't imagine what it would be like in the middle of winter.
