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: Muppets from Space
Big Lipped Alligator Moment: The "Celebration" song sung by the aliens when they finally show up. Of course, given that they are just as bizarre as Gonzo himself, it is perfectly in character. But the entire plot comes to a halt for the duration of the song.
Critical Dissonance: Everybody complains about this movie. Of all the Muppet movies to date, this is the one that everybody claims to be the worst.
Tear Jerker: The end where Gonzo almost leaves with the aliens.
There's a moment early on where Gonzo looks at pictures of housemates with their family members (Kermit with Robin, Miss Piggy with her nephews, Fozzie with his mother) and then at a picture of himself, which shows him to be completely alone.
Gonzo's dream in the opening.
The Woobie: Gonzo, between his longing to have a family and his determination in the face of skeptics that he's an alien.
