I'm still watchin, I'm part of the crowd that gets up at 4 am for work, works 10 hours +, drives a little over an hour to get home, get to softball practice or games, get dinner late, get home around 10:30 pm, get kids in bed, get showered, get to bed, do it again the next day...
I watch about a half hour at a time and just finished the first one. I too have been wonderin how acurate the details of the feud. If its true, there were hard feelins initially over the desertion, then some other details over a period of time and finally the daughter was the last straw. It seems (at least as its portryed) that Hatfield was really tryin to stay out of McCoys way and generally let him be, but when it came to any of his he wouldnt allow any of them to get shorted in any way and would go to any length to the point of ruthlessly defending family.
This is what I get from it thus far... must keep watchin.
