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 movie is highly quotable due to the overzealous amount of Narm it features. YMMV, but any party who watches it is bound to have an in-joke one point or another that originates from the movie's high-quotability.
Squick: Dex and Sunshine's flirting can be this if you're aware Hilary Duff would have been 15 at the time she recorded her lines.
Uncanny Valley: In spades between Sunny's cold dead eyes, the hideous human shoppers and stiff-as-rocks or seizure-like movements from everyone in the cast. In the case of Mr. Clipboard's spastic movement it could be foreshadowing the fact that he's a robot.
Vlad Chocul, the only gay character, is an over the hill chocolate bat with a bit of a stalker vibe.
The Nazi undertones of Brand X that aren't really undertones. Such as systematic murder of the various icons, flatout attempted genocide, their mannerisms and blatant accents. And the fact that their method of trying to kill Dex at first was by tossing him and Dan into a dryer to heat them to death.
Dr. Si Nustrix, is a Jewish caricature that panics and shouts every line. He's the one who announces, at the last minute, that the protagonist is also Jewish.
Kung Tofu, the Hairless Hamster Henchmen, and the Lunch Lady are blatant caricatures of various East Asians.
