Get a free on-demand movie every month. Unrated Riddick is an option but after watching the free 10 minute preview I opted for "Man of Steel" instead. Like the Riddick movies n all but LOVE Superman ones more Will hit free on-demand eventually. Still waiting for the first Hunger Games on free on-demand too. That's taking longer than most every other movie for some reason.
