SAVE DEADWOOD. HBO has so far failed to exercise its options on the cast's contracts for a fourth season of "Deadwood". The drop dead date to do so is June 11, 2006, which is also the date on which Season Three premieres.
This means no Season Four, even though Season Three had already finished production when the decision was made!
It's not necessary to explain on this page why Deadwood shouldn't be cancelled. You know why you're here.
