On a 2011 appearance on Ellen, for example, Whitmire's Kermit complained that he "is often mistaken for a green fire hydrant" and bemoaned his relationship with Miss Piggy. With his misery seeking company, he appealed to the studio audience, "Maybe some of your audience has actually dated a pig". Finally, when Ellen kissed the little green Muppet on the lips, he excitedly asked if he had turned into a prince. Upon realising he remained a frog, he sighed. "Oh, well." But it all simply seemed like part of the Kermit bit. The audience ate it up.
The 2015 ABC reboot of the The Muppets, meant to be a more "adult" portrayal of the fuzzy gang, was a different story. The show received a middling 62 out of 100 on Metacritic, a website that aggregates television reviews. Many of the reviews pointed to an angry or depressed tone to the characters, specifically in Kermit and Miss Piggy, who break up in the pilot.
Slate's Willa Paskin wrote, "The Muppet who comes off worst is Kermit, who spends his days sneakily managing Piggy's moods, working up the nerve to disobey her, a mild-mannered middle manager. His voice, previously so adorable, began to sound to me mealy and weak, like the vocal equivalent of pleated khakis."
The show was cancelled after one season. While it's unclear what creative role Whitmire played in the show - he was not credited as a writer - it is clear is that critics didn't like this new Kermit.
Even with the failure of a fairly high-profile network television programme, the termination of Whitmire had gone relatively unnoticed by the general public until last week when he published the blog post about his firing. It came a few days after his replacement, Matt Vogel, was announced as the new voice of Kermit.
"I would never [abandon] Kermit ... because to do so would be to forsake the assignment entrusted to me by Jim Henson, my friend and mentor, but even more, my hero," Whitmire wrote. He said he suggested "multiple remedies to the company's two stated issues, which had never been mentioned to me prior to that phone call". But days later, Disney executives gave the New York Times a more detailed account behind the decision.
Debbie McClellan, head of the Muppets Studio, a division of Disney, told the Times that Whitmire displayed "repeated unacceptable business conduct over a period of many years". Some of Henson's family members told the Times they agreed with the decision to replace Whitmire.
"He played brinkmanship very aggressively in contract negotiations," Lisa Henson, president of the Jim Henson Company, and Jim Henson's daughter, told the Times, adding that Whitmire staunchly opposed casting an understudy for Kermit.
