This movie, for me personally, had no meaning at all. The only characters I liked were the kids, and the story made being a parent seem like a thankless, horrific thing as all kids do most of the time is be annoying. I did not understand the ending. I read that it was open to interpretation; well I want my endings interpreted after investing that much time. Netflix owes me over two hours I will otherwise never get back! Olivia Coleman is wonderful as always but sadly I hated her character!
