I like this, though I have only seen the first five or so episodes. No surprise the male lead isn't from the US though.
Things tend to be telegraphed and I suspect there will be a large number of plot twists that don't make logical sense but I'm sticking with it.
[spoiler]I don't think the black Marine is dead, even though we saw him being buried, and he will have needed a fair amount of facial reconstruction after the beating he took.[/spoiler]
