The unacknowledged subtitle of Channel 4’s new reality series Eden (Mondays) is Die, Hippies! Die! Obviously they’re not going to admit this because that wouldn’t be right. But I’m sure Channel 4 is hoping that a terrible Lord of the Flies-type scenario will unfold for the 23 victims who’ve volunteered to get back to nature on a remote Scottish peninsula for 12 months, in which they hunt one another down with sharpened sticks, with hideously watchable consequences.
