Cons:
I didn't give a damn about Burt and Vicky, they weren't the most interesting characters, or the sharpest tacks in the box, which ultimately led to my not caring if they lived or died. The Extras aren't very good actors. The plot could have been FAR more complex and the characters more developed. The ending was lame and offered little in the way of closure (Job and Sarah seemed awfully... well, normal for kids who had seen their parents murdered.)

Pros:
John Franklin; suffering from HGD he had the appearance of a very haggard child, both old and young at the same time, which was perfectly fitting for the eerily convincing, fully committed way in which he delivers his lines. You get the feeling Isaac really believes the things he's saying and it's pretty hard, at least for me, to not feel sorry for him when he is betrayed by his flock and winds up waiting for the god he loyally served to devour him. The character of Isaac was truly fascinating, it's a pity the audience didn't get to see more of him and learn more about him (going back to the lack of depth in the story line.)

Courtney Gains; fascinatingly odd looking, he perfectly portrays Malachai as a blood thirsty, power hungry, "Lord of the Flies" type who would be far better off if he were as intelligent as he is ruthlessly ambitious. Another character that deserved more attention.

The two characters are also well presented as polar opposites of one another, in personality that is. Malachai is all impulse, rash action and brute force. Isaac is considerably more subdued and clearly relies more on craft and intellect than physical strength. I also noticed that Malachai carries a knife at all times, whereas, Isaac is pretty much the only one of the children that never touches a weapon (if that was intentional on the part of the writer it was brilliant.)

p.s. I can't help but feel sorry for John Franklin, he was a truly gifted actor and his career should have been so much more than it was... I also admit to having an inappropriate crush on him.
