Awhile back, Supernatural creator Eric Kripke revealed that he had a concrete 5-season plan for the run of the series.
Kripke's contract with the series is also for 5 seasons.
However, a 6th season is looking increasingly likely; both series stars Jared Padalecki and Jensen Ackles are contracted for that additional, 6th season.
So my question is: Would you rather see the series run for the 5 seasons that its creator envisioned? Or...assuming the series stars are returning (though it's possible that creator Eric Kripke would not), are you game for a Season 6?
