Following Henson's death, veteran Muppet performer Steve Whitmire was named Kermit's new performer. Whitmire claims that Henson had seemingly intended to pass on the role to him before he died, though it was Jane Henson and son Brian who had selected him after her father's death. Whitmire's first public performance as Kermit was at the end of the television special "The Muppets Celebrate Jim Henson" in 1990. Whitmire explained that his main intent when he inherited Kermit, "was to make sure the character stayed the same and consistent, but didn't become stale and just a copy." Kermit's personality during Whitmire's tenure was widely described as more wholesome, lighthearted, and Pollyanna-ish than Henson's. Several critics of Whitmire's portrayal have come from the Henson family. Brian Henson stated that while Whitmire's performance was "sometimes excellent, and always pretty good", he also elaborated that "Kermit has, as a character, flattened out over time and has become too square and not as vital as it should have been." Cheryl Henson stated that Whitmire performed the character as a “bitter, angry, depressed, victim.” He remained Kermit's principal performer until October 2016, when he was dismissed by The Muppets Studio. Disney cited "unacceptable business conduct" as reason for the dismissal, while Whitmire claims the decision was made due to creative disagreements over Kermit's characterization and prolonged labor union negotiations that delayed his involvement in Muppet productions.
