“Kyle XY” — Season 1
Equal parts “Roswell” and “The O.C.,” “Kyle XY” starts off as a sci-fi mystery, veers off into a teenage soap opera and ends its 10-episode first season with a compelling cliffhanger. The series, which debuted in 2006 on the ABC Family channel, begins with a teenager wandering in the woods just outside of Seattle. When the authorities find him, he is naked, unable to communicate, and devoid of a belly button.
