It's a really good movie and is really worth your time to watch or even buy. The computers are dated but thats it. It's smart, exciting and very well written. Go watch it. Go now. Come on! And you call yourself a computer nerd. I'm so disappointed.
You should also watch Colossus: The Forbin Project :

And for good measure, you should watch the classic 2-part Bionic Woman episode "Doomsday is Tomorrow" - one of the coolest, scariest episodes of any TV show ever
