Smallville definitely casts a "Christ-like" light on Clark, especially early on in the series. Not only do they "crucify" him on a scarecrow stand in the pilot episode, but there have been many other instances in the (so far) 9 seasons of the show where there are supernatural occurrences that even comic-book physics or odd-colored Kryptonite couldn't explain. Instead of having only a recording of Jor-El to tell him vaguely about his origins, Jor-El is an actual entity that is a part of his ice Fortress in the Arctic and interferes/interacts with Clark's life. There is an episode that shows Jor-El traveling to Smallville long before and meeting Martha and Jonathan, essentially choosing his child's adoptive parents. Jor-El takes on a God-like role to Clark's Christ figure. Jor-El takes away his powers at one point and Clark dies, but is resurrected when Jor-El restores his powers. Clark goes to his father to beg for Lana's life when she dies, and Jor-El rewinds time, but insists that there will be a balance in the universe, and so Clark's father dies. As the show goes on, the parallel between Clark and Christ lessens, as Clark learns about the vast shades of gray where morality is concerned, and he struggles to maintain his absolute view of the sanctity of human life in the face of many different kinds of evil. He has trouble with the idea of the "Greater Good" when it means that individual lives are in danger.
