What movies got computers right?

boxturtleme writes: There have been several posts recently about how movies have gotten computers, hackers, and other geeky stuff entirely wrong. A while back there was an article on Servers, Hackers, and Code In the Movies and another on Usability [of a GUI] in the Movies. Now we all know that most movies out there that have anything to do with technology get some part of it wildly innacurate, though it often makes for a fun movie. But what movies got technology right? This could range from movies about the past that represent it correctly to modern day movies or movies about the future that slashdot readers think present something within the realm of possibility. With all the complaining about bad movies, I'm curious to know what the good ones are.
