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.
Hilarious in Hindsight: The scene where Mr. Clipboard stomps a bag of potato chips and declares "survival of the fittest" while there's shelves full of Wonder Bread behind him.
This isn't the first time Charlie Sheen voiced a dog either. He voiced Charlie in All Dogs Go to Heaven 2
Idiot Plot: Seldom do any of these characters truly think.
It's Been Done: By the time this film was finally released a short French film called Logorama about a world entirely made up of real life brands and mascots had already been released, even winning an Academy Award!
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.
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 Asian nationalities.
If you're an assertive and flirty woman you're an evil Nazi but if you're sweet and innocent then you're a good person.
The fact that the only two stable, sane people in the whole movie are the two golden haired, blue eyed protagonists while everyone else is at best comic relief and at worst an insuferable stereotype. The fact that the villains are Nazis makes one wonder if the creators were just plain oblivious to this. And no, Dex being jewish doesn't count because A) it's revealed at the last possible second and B) it's treated as a joke.
