are you just speaking of the first one? Lonesome Dove, not Return to Lonesome Dove or Open Range or any of those? I looked up Lonesome dove on netflix, it shows it as 4 episodes and each one is apx. 1-1/2 hr, I have it on DVD at home, I'll look to see if it has 2 parts and how long if it does. in the mean time just let him think he's right so you can have peace!
