Always rented out at Redbox locations

This movie must be good...
There are three Redbox locations around my immediate area. THE BLACKOUT is always rented out. I've constantly checked the vending machines and it's never available. In fact, of the three vending machines, it disappeared completely from the list, meaning that dvd movie was probably never returned by the renter and the Redbox vendor simply didn't replace it. Of the other two locations, it's been rented out continuously for over a month.
