re: Hell on Wheels.
Yeah, AMC sort of did a dirty with it. They only had about 10-12 episodes per year. Since they decided to end it, they only ran 7 episodes last year so they could get another year out of it and have the final 6 (I think that is the correct number) episodes run this summer.
I don’t understand why these cable networks have such short seasons of 6 to 12 episodes and then wait a year for the next group of 6 to 12 episodes.
I hate that too, and how they have to have their winter breaks. By the time the next half of the season starts, or a new season begins, I've forgotten what happened, and have to check online to refresh my memory.
