I had this on my TBW list for a while I got around to it this week. Excellent show! I like that there were many smaller mysteries to distract you from figuring out the larger one until the very end. I did not get that one of the twins was the bully, or that Perry was Jane's rapist, until pretty close to the end.
Actually the later is the only thing I didn't like about the series though. It's not that I thought it took anything away from the domestic horror, as I've seen some people posted. If anything it adds another layer to it, as you realize why he could just change or cut short those "business trips" of his. My complaint is that I can't buy the coincidence of Jane just happening to move to the same community he lived at, and just happened to befriend his wife's friend. I would have preferred there to be some sort of red thread to why their lives crossed path like that. Unless we're meant to read it as Jane having moved there because she suspected the rapist lived there and wanted to find him?
Anyways, apart from that it was a great show. I liked how you sort of feel everyone was a bit unbalanced and you didn't really know who would come undone. Except for Perry of course, I kept hoping he'd be the one to die but I thought I'd be disappointed.
I'm not even sure I want to watch the second season. I have a pet peeve of book adaptations getting sequels.
