The net was... well I won't discuss it much hehe. Not my fav.
Hackers, great campy movie. I loved the 3d 'fly through' of a server.

And the badguy jumping out of a limo... to ride by on a skateboard.. then jump back in made me crack up to no end.
Die hard 4.... I just kept thinking of him from the Apple vs PC commercials. That's all I could think of. Didn't he USE a mac in that movie too? I've noticed that as a trend in a lot of hacker movies, they use a Mac. Even though.... macs are the minority for such an endevor, no offence to those of you who DO use mac.
War games.. groovy.
Firewall, that was interesting. It was the Harrison Ford one right? Where he used a broken open scanner, connected to an Ipod to 'download' the images of the passcodes from a screen? I don't know if such a hardware hack is easily possible like that, but it was a cool add in I thought.
Matrix, gotta love a movie that espouses the psuedo gothy hacker. Especially one with a chick in tight leather who uses nmap and then an actual exploit. CRC32, or sshnuke. Liked Mouse too, he reminded me of my old German roomate. Pervy little guy, but lovable.
Swordfish was ok... I like Haley.
