1. Sex isn't something to be taken lightly. There are consequences, and it's important to be aware of them and to be prepared to deal with them. And it's perfectly okay NOT to have sex.
2. Listen to your parents. They're not perfect; adults make mistakes too, but there is much to learn from their knowledge and experience. I really like the fact that the kids on the show treat the adults with respect. 3. A main plot line on the show is a man who fathered two children as a teenager and is struggling to figure out how to be a dad to both of them. In one episode it's revealed that he wanted one of the mothers to have an abortion, and the young man is devastated when he learns he might never have been born. When the boy learns that his girlfriend might be pregnant, he agonizes over what might happen and it's clear that abortion would not necessarily be a good choice.
Plus the actors are good, and the coastal North Carolina setting gives it a nice A Walk To Remember kind of feel.
