Save one performance and the decently cool setting, I really don't think The Children has much to offer. I've seen this British film twice now, and maybe I'm missing it, but I don't see how this is remarkable in any way whatsoever. Save your time and spending it counting stars or something.
What's your viewpoint on this British flick?
