The first four seasons focused on Clark and his friends' high school years. Since season five, the show has ventured into more adult settings, with some characters attending college. Recent seasons have seen an increase in the introductions of other DC comic book superheroes and villains.
Clark's only allies were the lovely Lana Lang, for whom our hero carried a secret torch, and aspiring entrepreneur Lex Luthor, whose life Clark had saved. Just as the soon-to-be-villainous Luthor was essentially a comic character here, so too was the young Clark Kent, miles removed from his adult "Superman" alter ego. Indeed, the series executive producers, Michael Tollin and Brian Robbins, prided themselves on the fact that their version of Kent was never seen wearing the traditional Man of Steel cape and tights. Opening to excellent critical and audience response, Smallville ended up as one of the jewels in the WB Network's crown during its first season on the air.
