While every episode has charm, three stand as high-water marks for superhero television.

The emotional core of the first season lies in the relationships, specifically the dynamic triangle of Clark, Lana Lang (Kristin Kreuk), and Lex Luthor (Michael Rosenbaum).

While Clark and Lana provided the romantic angst—the classic trope of the boy next door pining for the girl next door (who happens to wear a necklace made of his only weakness)—it was the bond between Clark and Lex that gave the show its weight.

Season 1 presents Lex Luthor not as a villain, but as a tragic figure seeking redemption. We meet him as a bald, lonely billionaire trying to step out of his father’s shadow. His genuine desire to be a good person, and his immediate friendship with the boy who saved his life, creates a palpable tension. Watching Season 1 knowing what Lex becomes is heart-wrenching; the season meticulously plants the seeds of distrust and obsession that eventually bloom into villainy. It is perhaps the best adaptation of the Clark/Lex dynamic in the character's history.

You cannot discuss Smallville Season 1 without discussing Lionel Luthor (John Glover). As Lex’s monstrous father, Lionel is a cold, manipulative billionaire who makes every scene feel dangerous. He arrives in Smallville to destroy the local agriculture and build a fertilizer plant. His war with Jonathan Kent (over land, values, and the soul of Lex) provides the show’s political commentary.

The season shows Lex trying to break free from Lionel’s shadow. In "Zero" (Episode 19), we learn Lex may have killed a man in his past. The show masterfully keeps you guessing: Is Lex a victim of his father’s cruelty, or is the villain already inside him?

Smallville’s first season (2001–2002) establishes the show’s core premise: a teenage Clark Kent growing up in the fictional town of Smallville, Kansas, learning to control emerging superpowers while navigating high-school life, friendships, romances, and the slow unspooling of his extraterrestrial origin. It set the tone for a character-driven, serialized take on Superman’s origin that balances teen drama, mystery, and occasional action.

What makes Smallville Season 1 stand head and shoulders above other teen dramas is the casting. Every actor brought depth to archetypes that could have been cartoonish.

Before the Arrowverse, before gritty reboots on Max, and before Robert Downey Jr. donned a suit of armor, there was a dusty cornfield in Kansas and a teenager named Clark Kent. When Smallville premiered on October 16, 2001, on The WB, nobody could have predicted its impact. Smallville Season 1 was not just a TV show about Superman; it was a revolutionary rethinking of the origin story. It traded the phone booth for the loft, the cape for a red jacket, and the "Truth, Justice, and the American Way" mantra for a far more human question: "What if the world’s most powerful being just wanted to be normal?"

Twenty years later, the first season stands as a time capsule of post-9/11 optimism, early 2000s teen angst, and the foundation of every superhero show that followed. Here is your complete guide to Smallville Season 1.
