Martha's interest in Lionel is like watching a dangerous animal; "It's that attraction you have for a very beautiful, dangerous animal. You know you can't stop watching it, but at the same time you feel, 'Oh my God, he's going to kill me.'" O'Toole also said she believes Martha's motivation is to get close enough to Lionel to know what he is planning to do to Clark. When Martha left the show, writer Todd Slavkin said they wanted to give the character "more of a send-off" than they achieved on screen. Slavkin said they could do nothing equivalent to what they gave John Schneider because there were so many storylines by the season six finale they could fit nothing else in. The writers realized they could not kill off the character so they sent her to the U.S. Senate, creating a parallel to Clark where Martha fights injustice on the political stage. O'Toole and Al Gough said Martha has a small attraction to Lionel and that nothing serious would come from it.

Dries said this is embodied when he threatens Lana into marrying Lex, later revealing it was to protect Clark. Glover describes his off-screen relationship with Annette O'Toole the reason Martha and Lionel have such good chemistry. Glover said that when Martha and Lionel are talking to each other it feels as though he and O'Toole are sharing a conversation, and that trust is visualized on the camera. Reception For his portrayal of Lionel Luthor on Smallville, John Glover was nominated for two Saturn Awards in the category of Best Supporting Actor in a Television Series.

By season four, one reviewer said Lionel should have left the show after succumbing to his terminal liver disease in season three. Maurice Cobbs of DVD Verdict said Lionel was taking away from the primary characters' screen time in season four, and the producers should have killed him at the end of
