These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way.

YMMV: It's a Very Merry Muppet Christmas Movie
Broken Base: Either this is one of the better of the made-for-TV Muppet movies to come about in the 2000s, or this is a blemish on the Muppets' integrity. The majority of Muppet Freaks really love this movie, feeling it did a better job capturing the original dynamics of the characters and their interplay, as well as maintaining the same sense of mayhem and chaos the Muppets' humor is known for; however, a small minority of fans feel this movie has none of that, that the movie is dark, trite, tries too hard to make the Muppets seems relevant and edgy, and pushes the envelope way too far in how much adult humor the Muppets partake it.
Crowning Moment Of Awesome: Fozzie's heroic struggle to get to the bank in time. Sure, he fails at the very last second, but given that the entire universe seems determined to stop him, the fact that he even made it to the bank is damn impressive.
In probably the most heroic moment of any Muppet film, Fozzie runs through a hallway full of Frickin' Laser Beamsthree times. If that's not Muppet heroism, nothing is.
Doubles as a Funny Moment when we see Miss Bitterman's "Oh, that's gotta hurt" reaction each time when Fozzie does so.
The Muppets' Christmas show is an elaborate spoof of Moulin Rouge!, possibly the best Muppet parody in a decade. To wit, the scene makes fun of Baz Luhrmann's editing style (at one point Fozzie grabs Kermit by the neck with his cane and begins twirling him in circles just to make the camera spin dizzyingly around them), has chickens singing Lady Marmalade, Gonzo very appropriately dressed as Toulouse-Lautrec, and Miss Piggy as "Saltine", choking on the dramatic fog in her entrance and coughing uncontrollably (making a big laugh out of what was the most tragic scene in the whole movie). In the end, Miss Piggy brings the whole thing to a halt to scream at everybody to stop singing different songs at the same time.
Also the statue of Kermit seen in the film, which in a callback to The Muppet Movie, is dedicated to "The Lovers, the Dreamers, and you", a shout out to Muppet Fans as a whole, and to the song itself, as it was a Number One song at one point in time, sung by Kermit himself in the Muppet Movie. The song is still associated with the Muppets (and Kermit himself in particular) to this day.
Fridge Horror: In the world without Kermit, Rowlf is not mentioned or seen at all. Now take a minute to think about what happens to stray dogs.
Nausea Fuel/Nightmare Fuel: In the alternate reality, Rizzo has one of the worst fates; he's in Fear Factor as one of the challenges, where he's locked in a cage and the contestants have to eat him alive. And he didn't even know about it.
Squick: Pepe's methods of sucking up to Bitterman are a little disturbing, to say the least.
Cage dancing Scooter in the Kermit-less world also qualifies. In skin-tight leather, no less.
Tearjerker: The Muppets' lives in the Kermit-less world are almost entirely bad, but most are not wholly depressing. Gonzo and later Piggy, however, aren't so fortunate. The former is a homeless performer eeking out a pathetic living, and the latter is bitter and depressingly lonely.
True Art Is Incomprehensible: The original opening number for the Christmas show (directed by a French choreographer that Gonzo hired) was... decidedly un-Muppet-like. Case A: it had a Muppet throwing glass Christmas ornaments directly at the audience.
