The series follows the life of a teenage Clark Kent living in the town of Smallville, Kansas that is set at the start of the 21st century. It shows Clark Kent coping with adolescence while he is developing super powers (X-ray vision, super speed, etc.), exploring his extraterrestrial origins, and struggling to find his destiny.
When Smallville blasted its way into the TV universe, it offered the promise of a unique, coming-of-age take on the Superman story. Now in season 3, the show sometimes delivers on that promise but more often stumbles.
