Ugh... I hate even thinking about the Henson Company's CGI kid's shows like Dinosaur Train or Sid the Science Kid. I wish they had the brass to do a new show with Creature Shop creations.
Well, I applaud Sid for being digital Puppetry still using the Waldo system. I think it worked better for the Skrumps... but Dino train, much as I like the show and the characters, it's Henson in production company and the creation of a freelance employee only. Thing's animated in Singapore and voiced in Canada... not even with a single Henson employee voice actor. I mean, I LOVE Ian Cortlett and Kathleen Barr (wish they'd get Scott McNeil to do a voice in it), don't get me wrong... but it really feels like something Henson is just a production company of. And it's basically their staple franchise. There's so much merchandise and it does pretty well. They desperately want to make their staple Fraggle Rock, but it's going to be Dino Train.
You said "No one is EVER going to be happy with any Muppet film that isn't the first three," but I personally much prefer The Muppets to MTM; I've always found MTM a bit boring, mainly because it lacks an antagonist.
MTM didn't need a physical antagonist. It was all about Kermit's inner struggles and the realities of having big dreams... the hopelessness, the longing, the huge period of waiting for something to click... Not being able to get Manhattan Melodies out there fast was the antagonist.
Of course, I hold the first three films very dear myself, and don't think they can be topped, but also I feel that there's no need for them to be topped anyway. Like I say with Looney Tunes... sure, we'll never get another Chuck Jones or Bob Clampett or any shorts as great as those... but I LOVE stuff like Taz-Mania, Duck Dodgers, Tiny Toons... just don't do Baby Looney Tunes and Loonatics. Try. That's all I ask. That said, I really think this movie comes very close, as I do think that VMX and LTS come close on different angles as well, but feel a little too modern to really be classified the same for me. I'd say that The Muppets is my favorite Post-Henson Muppet Project (favorite Post Henson project period? Dinosaurs)... I'd put those three movies/specials together as my top favorites. I also love MTI. Just... never EVER get Tim Hill to direct again, easy on the Simpsons writers.
I kinda wanna see Brian Lynch have an angle on the Muppets. If there's anyone besides Jason I'd like to see work on the next project, it's probably him. I'm loving his work on the new TMNT one shot comics.
