More a minority position than an unpopular opinion, but: I have one hell of a time accepting resurrections if the death was carefully worked out and the resurrection occurs without due explanation.

Alfred's death may have been sophomoric symbolism, but it was enough a part of King's master plan (such as it was) that fishing him back from oblivion would be all but a frank admission by DC that King was wrong--that letting King carry on was wrong--at a fundamental level. On the other hand, King's Batman feels so little like "real" Batman that if everything King did were retconned in one blow it would strike me less as a violation of continuity than simplying bringing Alfred back would. At this time they appear inclined to do neither.
