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.
Crowning Music of Awesome: Whatever you feel about the movie, the soundtrack had a few dynamite songs. Standouts include The Closing of the Year (the opening and closing theme), Enya's Ebudae, and Welcome to the Pleasuredome during the final confrontation with the war toys. The very awesome Ear Worm from the "music video" is called "The Mirror Song," and was performed on the soundtrack by Thomas Dolby.
"Funny Aneurysm" Moment: General Leland's plan is obviously meant to be insane, but a decade after the movie came out unmanned drones controlled remotely and raining death on their targets became a major part of the US military arsenal.
Memetic Mutation: Ironically enough, not from the film itself, which has largely been forgotten, but the trailer became one of these for a while. The trailer was referenced by The Simpsons with Burns in the Williams role.
Strawman Has a Point: Leland's plan to make war toys (before he comes up with the concept of actually militarizing them) makes solid economic sense. Zevo Toys seems to operate almost entirely on making toys that would be considered extremely retro, and a handful of extremely common and oft-duplicated novelties. In the real world, such a company would probably crash and burn the first time the economy took a dip. And while his security measures are a little extreme, the factory apparently had no security before he arrived, with the response to industrial espionage apparently just to sigh and throw up their hands.
The military aspects of his plan also make sense. Managing drones is much cheaper than putting an army on the ground with all the logistics that entails and leads to fewer deaths of the military using the drones.
