I saw this advertising as The Vow was ending and was immediately attracted to it.
The people I've gotten to watch The Vow are just as excited to watch this.
I especially like the first episodes way of showing the experience/situation, and immediately following with the professional experts opinion on how and what was happening to draw these people in.
For quite some time I wouldn't have noticed anything wrong either!
I hope they continue on this journey showing how and where and why things went bad.
