I'm not a big western fan but I'm really getting into Hell on Wheels on AMC. It's a fictional story that follows the construction of the railway line in the US. It starts Anson Mount and Colm Meaney. It's interesting in that it follows the greed and corruption of the railway builders.
I've seen this show and should try and get back into it. I watched previous episodes and drifted away from it to watch other shows. It is a great story line and I like the competition between Anson Mount's character and Colm Meaney's character.
