The movie was partially responsible for creating the stereotype. This was 1992 and hacker culture wasn't yet mainstream.
I think that's the reason I don't have the affinity for this movie that many do - it created incorrect stereotypes which still persist today.
Tron is literally about a hacker.
Sneakers is about spooks wanting to be hackers and hackers wanting to be spooks.
Sneakers is the point where the militarization of hackers became mainstream.
Stereotyping isn't inherently bad, it's just lazy. That having been said, I think Sneakers gets them all correct.
