These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: The Muppet Movie
Award Snub: "The Rainbow Connection" lost the 1979 Best Song Oscar to the now-virtually-forgotten "It Goes Like It Goes" from Norma Raenote which, it must be noted, deserved quite a few awards, but "Best Song" is not on that list.
Doc Hopper's frog suit in his commercial is kind of creepy.
Miss Piggy's wide angry eyes◊ when she karate-chops the kidnappers.
It doesn't help when she's above them and says, "Oh, boys." When the camera pans up to her, she looks like a creature out of hell!
Seinfeld Is Unfunny: Alas, many of the jokes and wackiness have been copied by countless followers (both Gremlins 2: The New Batch and The Spongebob Squarepants Movie have done meta gags about their films being watched in theaters, for example), that, to anyone watching the film for the first time, it might seem less remarkable.
Visual Effects of Awesome: Kermit riding a bike near the beginning. Don't wonder how they did it, just accept it.
Actually, according to Frank Oz, the effect was relatively easy to do,*
Essentially, the Kermit riding the bike was a marionette, with the bike pulled along by an invisible wire
compared to the monstrous effort required to get Gonzo to float along on his balloons. But since the bike was the effect everyone kept gawking over, they included an entire parade of Muppets on bikes in the next movie. Just because.
