I love that movie. What I find most interesting about it was that at the time of its release, it was probably thought of as a typical kids' movie quickly to be forgotten, and yet by today's standards, it's almost a classic: characters you really care about, a non-obvious, somewhat plausible plot, and it deals with serious issues (automation vs. human control, the nuclear Cold War). If it were made today it would just involve lots of ridiculous made-up "hacker" crap with no connection to reality. But it would have good special effects.
In my personal opinion, very few "good" films have been made since the 80s. Lots of throw-away movies, but few films.
PS I just realized a neat little detail. I think the first scene with Matthew Broderick has him playing Galaga (or was it Defender or Space Invaders?). Anyway, it's a game about saving the world from aliens... Like in Terminator 2, in the first shot of John Connor in the mall arcade he's playing that defend-cities-from-falling-nukes game. It's the little touches like this that I miss about most modern crap!
