Kickass Screenplay Ideas Number 5ive (well, not really, but I had to)

There should be a prequel to Se7en called 5ive. In it, the John Doe character works his way through an earlier grisly series of murders, each inspired by one of the classic 5 Stages Of Grieving from the Kübler-Ross model of Grief Theory.

It would turn out that his dog had died.
