For $8 bucks a month I find it to be a great value, even if I only watch 5 to 7 things a month. To use OnDemand I would need Cable TV and have to pay $50 to $60 more.
I can imagine many wives not wanting to get rid of cable TV and just have Netflix. Maybe this was another factor why the OP canceled it or maybe he was just wanting to write an interesting blog piece and resigned up.
