Well, since Natasa has cited me as a part-time Marxist critic, I suppose I ought to rise to the challenge...
* The only thing missing from Deliverance is the pith helmets, because this episode is little more than a sad pastiche of Rider Haggard with pretensions to being science fiction. Our stalwart bunch of middle-class Home Counties adventurers find themselves ditched on a planet consigned to quaint notions of barbarism through the magically convenient means of 'a war' at some unspecified point in the past. Almost from the start we're told that whatever society there was has undergone a 'reversion to primitive', and it isn't long before we're comfortably assured that primitive means dangerous. The planet itself is dangerous, what with all that radioactivity.
Despite which, there are some local primitives still knocking around. First off, we have a bunch of men (plural), who are aggressive, inarticulate, and unaccountably hostile. What better excuse could you need for shooting them with impunity? Well, just in case, the script has one to offer - they like to steal our women. We don't see Jenna get abducted, but surely she wouldn't have gone off with them of her own accord? Heaven forbid! They don't actually do anything with her beyond sticking her in a tent, thus sparing all and sundry the anguish of singing Here Comes The Night.
As well as the men, we also have a Woman (singular), who is young, passive, demure, extremely well spoken and has somehow managed to keep all her teeth white. She instantly throws herself at the feet of our sturdy white giants and hails them as the saviours of her people, singling out Avon as 'Lord'. Vila and Gan presumably come from Another Place.
