With the season premiere of "Game of Thrones" right around the corner, I finally talked my family into watching the series from the beginning. On Demand had every episode of all 5 seasons available. That was last week. Today I went back to figure out how to fit 5 seasons into the next 3 weeks and to my surprise half of the episodes are no longer available. Season 5 is there but Seasons 1 - 4 have been cut up with only 5 or 6 episodes available for each season. What is the point of On Demand if you can't watch a show in it's entirety.

Because once the "Powers That Be" got us used to being able to put off a series and binge watch later.... They figured out how to monitize the experience by only giving "parts" of past seasons. The other episodes can often be purchased.

Or they are just missing again due to a system glitch, and will be restored shortly. Like they were for the people in this forum who had your problem a few months ago:

You were right, they are back.
