for me, that was the beauty of the show. i can only agree that the bulk of the show was full of droll cliché, but the whole take on guilt and morality and, indeed, the idea of a "second chance" was very intriguing. i thought about it for some time after listening. my assumption is that the people go back right to the moment when they were killed. from there, they had to make their ammends, one way or another - for better or for worse.

anyhow, just saying is all.
