My dad's bday was the other day and for his birthday a buddy of his gave him five big garbage bags full of DVDs he'd gotten from his grandfather's collection. A lot of westerns. I recognized Deadwood (the complete series) and asked if I could have it and he gave it to me. Why have Westerns died off in popularity? When it seems back in the day that was all they made.

Should I watch shows that I know were cancelled halfway through?

Isn't that setting myself up for sadness and disappointment?
