It looks as though this third season … MIGHT be its last.  There seems to be a lot of speculation out there about whether a fourth season may be possible via streaming services like Netflix or Amazon Prime.  I myself can’t tell if I should be optimistic … apparently if NBC cancelled the show early this season, the producers “have time” to shop for another carrier?

They say that the show has a fervent cult following, but no wide audience.  I’m forced to admit that this makes sense to me — the program’s gore probably turned off some viewers; its unexpectedly slow pacing (which allowed for a cerebral script) probably lost even more.
