Heh, yes, I *do* feel as if Supernatural has violated its implied contract as well. Of course, I suppose that we viewers only notice this if it takes the show to a place that we really don't like! But for me, the fact that SPN has gone from being a road-trip show about urban legends in the first season, to basically Hellblazer-lite in the fourth, combined with race and gender issues that REALLY bother me, is seriously doing away with my love of the show.

I was fortunate with SGA that the stylistic and premise-related changes in the third season actually appealed to me. But I can totally see how they would not have done so to many fans, and I don't blame people for leaving or disengaging with the show at that point.
