Started watching, seemed ok, but the more episodes I watched, I realised that the writers had made the protagonist to stupid in his actions, personality and character that I just couldn't root for him to get the money he's after. Maybe they had a reason for that, but I can't see it. The Australian actors/characters are good for their part in the story, and I'm just watching the rest of it purely for closure. I doubt I'll watch a second season, should it ever come to be.
If they'd written it as a pure mystery; there's enough of a plot for it to have been rather good. I think, also, there's enough quirks amongst the town's population to have given it something different to the usual drama we see nowadays. Ah, well.
EDIT:
Ok, just finished watching ep12... The unraveling and solution to the ongoing mystery was a surprising twist, and I'll probably watch a second season. Still don't like the protagonist, though, but I'll knock my initial review of 4 up to 5.
