I have no idea what the motive is for this show, but the idea of watching bodies decompose might have merit. There is a place in the US where there is a very large farm that has a variety of landforms and is very hilly. They place dead bodies in all sort of places around this farm to simple decompose naturally. They are inspected on a regular basis, and pictures and observations are carefully made. You would be surprised at the number of murders that have been solved because of this data. They can almost pinpoint the hour of death and the hour of "deposit" when a body is found, even though it was placed there years ago.
