That was a subtlety that was LONG gone with Henson. It had more of that Muppet feeling than the past projects, but that's another thread all together. You cannot replicate something when someone leaves a project or dies. And as I said, no matter how hard you try, your personal style fails you. I'm surprised there weren't more Star Wars references in the film other than the inclusion of the WDW Muppet Mash up figures. They LOVE Star Wars too. HIMYM is FULL of SW references... to the point they're major plot points in certain episodes (Barney and Robin's Stormtrooper argument/ Barney's theory about how his first steady girlfriend hating Ewoks means she's older than she said she was).Oz is acerbic, witty, and has a dark sense of humor. He's not jaded. He's a realist. He has a point, although I don't entirely agree with it. The biggest problem I had with "The Muppets" is how it was blatantly emotionally manipulative. It lacked the subtlety of Henson-era Muppets. But I accepted that, good with the not so good, and enjoyed the movie anyway.
I think Frank was at a loss of words, and had a certain feeling he was trying to express that couldn't be explained. I'd wager to say he meant something along the lines of this...
This was a part of his past career that he's since moved on from, but still has a huge personal and emotional impact on him. He's glad that people are keeping Jim's vision going, but feels that it isn't the same because Jim's no longer around. Jim would have done something much different than this film, something more experimental. This is more of a nostalgic fan driven project, while Jim was a forward thinking guy who was more interested in penetrating different markets with different visions and was always out to do new things. And of course the whole "I know the subtleties of the characters because I was them, and my close friends were the others." Not to mention the "can we PLEASE talk about MY projects now?" He can't be too happy if he's pegged as one thing and one thing only. Remember when they were filming the movie with Marlon Brando, and Brando kept calling Frank "Miss Piggy," to push his buttons?
But here's the thing that I wonder... what exactly did he think of VMX, KSY, MwOz, and LTS? I can't say he'd be too fond of those, but no one asked. I think we can agree that he hated working on MFS, as pretty much EVERYONE did. Heck, don't Steve and Dave kinda act like it's their old shame?
