* SugarWiki/AwesomeMusic: Music/Blink182's "Aliens Exist" was used in the marketing, and it perfectly captures the tone of the film, with memorable lyrics and a hardcore riff.
* ClicheStorm: Deliberately uses a lot of cliches from 1950s alien invasion movies. However, some found this palette swap a little boring.
* EnsembleDarkhorse: The Alien Dog is a fan-favorite for being a great homage to ''Franchise/{{Alien}}''.
* HoYay: Chuck and Lem are basically flirting through the whole movie. Some of their dialogue {{lampshades}} this.
--> '''Skiff:''' I think Lem's saying [[ItMakesSenseInContext he wants the closet]].
* RetroactiveRecognition: Creator/JamesCorden voices one of the military officers.
* SignatureLine: "That's a funny place for his antenna".
* TheyWastedAPerfectlyGoodPlot:
** They could have done so much more with the HumansThroughAlienEyes concept, thrown in some weird alien biology, a few alien customs, and it wouldn't spoil the 1950s gags excessively, but the alien world is almost identical to Earth, making the "alien invasion role-swap" premise little more than a matter of swapped aesthetics.
** Furthermore, the aliens' ignorance of the size of outer space could have been an interesting commentary on the close-mindedness of humankind, but it is ultimately thrown away after Lem attempts to make his speech.
%% * SugarWiki/VisualEffectsOfAwesome: This movie looks well done for a rather small budget.
* WhatDoYouMeanItsForKids: It's a fun kids cartoon movie, but has some raunchy innuendos, not to mention it's from one of the screenwriters of the ''Franchise/{{Shrek}}'' franchise.
