However while we did see small cameos by characters like Pepe and Big Mean Carl and Bobo's role was excellent too, it would have been nice to at least had some token references in recognition of the short lived revival attempt Muppets Tonight. Would Gary and Walter have enjoyed that even if they preferred the original Muppet Show?
I'm probably the ONLY person here that's not begrudging the lack of newer characters, only because we had Rowlf and Scooter as something besides background characters standing there to say "nostalgia." Rizzo has been a huge part of the last 3 theatrical features, but it wasn't even until MTM when Rizzo actually became more of a character. In GMC, he had like 2 lines... I don't even know if he was a character when TMM was filmed. I would like to have seen more Gonzo screentime, but those were obviously in the deleted bits. The fact he contributes to the ending's punchline is the only reason I forgive his smaller role. And you gotta admit, at least there was a nice allegory for the fact they were trying to reinvent Gonzo in the 90's, so he doesn't do anything Gonzo-like. We all love him more when he's doing stupid crazy stunts.
A nice quiet scene with Kermit and Robin talking together, just Kermit trying to be optimistic for the success of the show and Robin reassuring him that everything will be great now that everyone's together and it ends with the two of them just watching everyone work.
Here's the thing about Robin. His biggest movie role was in MCC... his second biggest was The Muppet Movie where he asked Uncle Kermit if this was exactly how the Muppets met. Like I said, I can't begrudge a film for not having certain characters, especially characters who never had big roles in a movie anyway. I agree we needed a full Electric Mayhem number (and we were going to get one under one pass of the script), but the fact they actually sang a line is an improvement over the last 3 theatrical films. Heck, last line Dr. Teeth said in a theatrical film was "Shalom" and you never see them again.
But you figure... a LOT of the characters in the film were NOT in any of the original films. And even if they were, they were background characters. Link had some lines in a song... we saw Wayne and Wanda... surely we can forgive a couple absentees for some old school characters that got their first substantial screen time.
Overall, there's nothing wrong with the film that couldn't have been solved with more movie. More Muppet interaction, more characters, a stronger ending... if the film was 2 hours (which it should have been) it would have had all of it. It doesn't severely need it, but the major scenes that were cut were indeed more Muppet interactions (the jail sequence, the awards show, a rehearsal scene).
The improvement that needs to be made for the next film is that they need a story they can tell in 60 minutes, leaving at least 30 minutes for Muppet Wackiness.
