I saw the movie again today. Sadly the audience was quite muted except for a vocal bunch in the front row, only a few jokes got everybody in theater cracking up.
I forgot how much the movie relies on 80's references. Not that it's a bad thing, but it's strange to consider how Segel and Stoller are viewing this from the perspective of the general public: lumping the characters in with the pop culture relics of the 1980's. Yes, it's woven into the narrative, but they're clearly attempting to help with the nostalgia. And... that doesn't work for me. Of course, I was born in 1988, so I'm not the exact target here. It's just that a huge part of the movie is "Muppets = 1980's" that is actually the most troubling thing for me.
Thankfully aside from Kermit filing through the rolodex, they ease up on the "LOL Muppets are dated" humor and have an updated Muppet Show play out before our eyes.
Richman's rap works if you view it as a joke rather than a full-blown musical number (because it really is reduced to a mere minute of screentime), but I can start to see where you guys are coming from with the "he can't laugh" bit. Deadly alludes to it in his big moment... and suddenly the seams are showing. I'm fine with "Maniacal Laugh" being a very random joke, but throw the line, "It's an idiom you idiot, 'cause you can't!"... whoops! Of course, you can still assume, but it would have been best if they included it, yes.
The wedding scene... not so much. Piggy mentions it in her scene in Paris with Kermit, that settles things. Anything else would have been superfluous.
Otherwise, I still enjoyed it. I think I'll wait for the Blu-Ray in March to see it again.
