It's too late now, I didn't think to join and post this here sooner, but I'm curious.
AMC/D* was showing Walking Dead Season 3 On Demand for about two weeks earlier this month. They are not there now.
What was interesting (and annoying) was that they had every episode but the last one. I can only guess that this is an attempt to get us to set our DVRs for the repeat of the series that will come before the new season starts to make sure we keep watching.
This is the first series I've watched On Demand, except for catching up on Breaking Bad 5A earlier this year, which came on before Netflix.
WD isn't available on Netflix yet, and I'm guessing when it is, all 16 episodes will be there.
Does anyone know what this is about?
