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.
Narm Charm: Ooooh yeah. Hackers is one of those movies you show someone if you're trying to get them to understand the entire concept of Narm Charm.
So Bad, It's Good: Let's face it - this film is nowhere near perfect, nor is it anything close to a realistic depiction of hacking/cracking. That being said, it's still an enjoyable film. It's a Cult Classic for a reason!
Strawman Has a Point: The FBI are supposed to be the oppressive authorities going after the teenage rebel hackers. It'd be a much better message if said hackers weren't casually breaking into other people's computers for personal amusement (and wealth), causing serious problems for an agent who publicly denounces hackers and if the movie didn't start with the main character causing serious economic damage through hacking.
It helps a little that most of the cyber-crimes committed by the hackers the movie focuses on are counteracting the ability of major corporations to rip off ordinary people (the payphone trick), the serious economic damage was caused by the main character when he was a kid, they punish the agent for making gross generalizations about all hackers rather than the malicious ones (that his dumb ass hasn't noticed are in his own organization) and when one of their own actually makes a bad move by hacking a bank, they pretty openly disapprove. All this would probably matter a lot more if all the hackers in the movie who aren't that one group of friends weren't pretty obviously turning a profit on stuff that is probably at least partially related to hacking, and at least a few in the "Hackers of the World, Unite" montage didn't look at least as much like white collar criminals as the villain.
True Art Is Incomprehensible: More straightforward than most; the abstracted visual depictions of hacking are meant to be from the perspective of the hackers, as a way to illustrate the way the characters in the movie interpret what would otherwise be boring, uninterrupted lines of programming that most audiences would find dull. The blocky grid that houses the Garbage file was chosen to evoke the image of New York's city streets and buildings to suggest connections and locations as the characters relate them to hacking.
