The '90s Film:  Back in the day, before Google, eBay and Youtube, the Internet was the playground of anti-establishment geeks, all going under silly names like Crash Override, Acid Burn, Cereal Killer and The Plague.

Hollywood thought: that sounds cool and made a film that, to all intents and purposes, consists entirely of people typing.  See also: The Net.

If They Have To Remake It: At least make it look interesting, maybe by having the hackers actually need to get inside the computers to do their dirty work.

...Hang on, that's a bit like The Matrix, isn't it?  Or Tron. Oh well, back to shots of people typing - although at least nowadays they can do it on a iPhone.
