Paskin's criticisms of Miss Piggy's newer, more neurotic portrayal were echoed by Maureen Ryan at the Huffington Post.
"TV can always use more imperious divas, but as depicted in The Muppets, Miss Piggy isn't magnificently and amusingly self-absorbed - she's simply mean, and not compellingly so," says Ryan.
"Part of the show focuses continually on Kermit's point of view, as he nervously reacts to her displays of unreasonable pique and rampant jealousy, and it's a dynamic that both gets old fast and denies the full comic potential of Miss Piggy's insecurity and grandiosity.
"It's strange that a comedy that wants us to peek into the minds under the felt allows one of its most famous characters to be so one-dimensional."
HitFix reviewer Alan Sepinwall also bemoans the "awfully cynical and bitter" reincarnations of the characters, but holds out hope the show's creator, Bill Prady (Big Bang Theory) will take early criticisms on board.
"There are a few funny moments here, and Prady's both a smart writer and a flexible one" Sepinwall says.
"If you compare the Big Bang Theory pilot to any episodes made after Amy and Bernadette became regular characters, they're practically two different shows.
"Given his history with the Muppets, and the fact that this show was a bit rushed in development (the final pilot wasn't made available to critics until a few days ago), I hope he ... will be able to figure this one out."
