I found most of the characters thoroughly unpleasant. I wasn't hoping for anyone to get out safely. Without any characters I cared about, I was just watching crappy things happen to crappy people who probably deserved everything they got. I'd rather read Gone Girl, which was essentially the same plot with more interesting characters. The convoluted story bugged me a bit as well. There were a lot of twists and turns, but having to do a 180 every ten pages got boring really fast. I wanted to like this more than I did, and I can see how people would, but it just wasn't for me.
