There might be a good show underneath all this garbage...... I agree that this is an interesting concept.
Yes this is obviously heavily scripted, and a lot of the situational stuff is incredibly stupid but if you can get past all the stupid stuff like marauders (one of the lamest things ever shown on TV) there's some potential here to create a good show and maybe give the viewers some useful survival information (which is why i tuned in - i've watched the first 2 episodes) As it stands this is a less believable version of the TV series Jericho gallivanting as a "reality show" So far most of the "characters" are uninteresting (with the possible exception of the engineer and mechanic who have built a few heavily scripted "devices" with a collection of materials 2 good to be true in an actual survival situation....
My advice is change the format of the show and give us some useful disaster survival information and cut out all the stupid garbage.
