I never heard of a premise like this before, so I have to give it credit for that. On the other hand the ending was predictable. Then there's the famous "what's my favorite color" line.
Darin Brooks was exactly what he was supposed to be which included some great funny moments. He and Natalie Hall had great chemistry. Jen and Kevin's story was super sweet. Jen was a different person with Bryce and not very likeable. Not just sad, but weak. I think that's great story telling because that's what guys like that do to nice ladies.
Points off for makeup especially on Natalie Hall. There were a couple of scenes where I thought she was just about the most beautiful woman I've ever seen, but in most scenes, especially at the beginning, her facial tone was way off. It looked like she used a cheap spray on tan and then added too much red on her cheeks. It was very distracting.
