Question to everyone who really know this "reality TV' stuff and especially the the Colony show. How muych of it is real ??

For example:

1 - They ate rats. Did they really do it or were the rats replaced by some chicken nuggets ?

2 - Professor John C .. I got senmtimental when he talked about his deceased son. Was that real ? I like to think so .

As a matter of fact I liked John C; a guy with a big brain and a big heart.

3 - The gasifier in the truck !!! The lower barrel which contains the fire that should heat the coal in the internal barrel .. that outer barrel had no holes for ventillation !! So , how real was that gasifier ??
