Traveling by map worked a LOT better than than the rest of the car montage. Even if they had to do a montage to pick the rest up, they could have handled it a bit better. Still think it could have worked as a jump cut.
I still do like MFS a lot, but listing the problems would take all day. I really think they could have done the entire film without Kermit, Piggy, or Fozzie. I really don't like Piggy's role in the movie. There's a lot of great scenes with Gonzo and Rizzo, The Lab rats, Dr. VanNeuter, and some brilliant play between Bobo and Jeffery Tambor... but other than that, too many goofy experimental concepts (the 70's funk track), an overly labored script, and worst of all, a hack director that just didn't get anything just totally screwed up a decent film. A lot of the lost concepts of The Muppets were disappointing, but nothing half as bad as changing the ending from something wonderfully complex to something banal. Plus, at least with The Muppets, the stuff was cut and we have some hope of seeing it some day. There was NO excuse for cutting that Traveling Matt Cameo. None.
Plus... as far as cameos go, I'm glad that Jason and the rest had some muscle in Hollywood to get some of their friends in it. I LOVE Jack Black, Kristen Schaal, NPH... Selina Gomez's 20 seconds is far more bearable than Rob Schneider (oooh the rant I want to do on him). The cameos in MFS were very sad, and a sign that the whole movie was treated as an after thought by studio and Henson alike.
And quite honestly, I kinda wish Muppets IN Space was made instead.
