To be fair, a stranger in a strange land is an essential component for most television pilots. There has to be a reason that the series started today of all days. In every teen drama, this tends to look exactly the same, give or take one plot point: our protagonist is the new kid in school.
The O.C. and Gilmore Girls accomplish this by sending the protagonist from their home on the wrong side of the tracks to a school on the right side of them. In Freaks and Geeks and Dawson's Creek, the new kid has always lived in the respective school district but is finally diving into world of high school and puberty. Sometimes this new kid is a man in his 40s (Friday Night Lights) or a debutante returning from rehab (Gossip Girl).
Regardless of the hero's identity, though, he or she is, in one way or another, the new kid in town.
