This has to b one of the best series I have watched in some time , besides it being historical and telling the story of how the railroad was built , the lives lost , battles with Indians, the racial injustices the elements and corruption, u just get so caught up in the characters , Cullin Bohannon is the driving force and pushes both sides , you will laugh and shed a few tears but u will never find yourself bored with this series , I tried to stretch out season 5 , 3 days lol , .....Great show and a great ending.
