Query: Great chemistry

Matt and Catherine are a great couple -- even if they're having trouble convincing each other! One of the most likeable elements is their history together. Rather than being two strangers falling in love almost instantaneously, they grew up together. An interesting twist on the girl-next-door phenomenon.And, the family dynamics are great -- a bewildered mother and meddling brother. I came to love this family and rooted for Matt and Catherine throughout.
