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.
The fact that all of the space shots are recycled from the old Battlestar Galactica is pretty funny to begin with, but it all got even funnier — or at least, that bit more ironic — when the final season of Battlestar Galactica (Reimagined) had a major arc involving, yes, a mutiny in space aboard Galactica, which was also spearheaded by a power-hungry Machiavellian type and a trusted member of the crew who walks with a pronounced limp. Plus, the Captain bears an uncanny resemblance to the Galactica 1980 version of Adama.
All the jokes about how the inside of the ship looks like a brewery are even funnier in light of the 2009 Star Trek film, in which the engineering section of the Enterprise really is a Budweiser brewery.
Ikea Erotica: The sex scene between Dave & Lea can be seen as a visual representation of this. It doesn't really show anything and is rather boring (though a brief glimpse of Grandma-Daughter nipple was cut from the MST3K version).
Crow: Uh, could you wrap it up, Chunky? There's a tour coming through!
Mis-blamed: David Winters is credited as the Director despite the fact that Neal Sundstrom really directed most of the film and a third, uncredited director was responsible for the stuff with the Bellerians.
Narm: All over the place, but one moment where Ryder screams before jumping out of the speeder stands out.
They Just Didn't Care: Continuity errors all over the place, most glaring in one instance where a supporting character who was just murdered appears as an extra in the very next scene.
Unfortunate Implications: The crew has the initials of the "Southern Sun" as in insignia on their uniforms. Good idea, except those initials happen to be "SS", as in the Nazi secret police SS. Not only that, they're also written in the typical lightning-rune way, and there aren't any crewmembers who aren't obviously caucasian.
Also the moral of the entire movie seems to be that, if you're opposing the law (no matter how oppressive, illogical or poorly written it is), then you're definitely in the wrong and deserve to be burned to death horrifically by some Aryan dude.
