First off I would just like to say that anyone who reads into this movie too much(ie try to take the validity of each and every aspect of the movie) will hate the film. Coming from a programmer and a computer enthusiast, the movie was great despite all the false statements, fake guis and totally bs methods of cracking. Quite frankly if you are one of my fellow computer geeks don't expect anything close to the real deal, it would never make a good movie for the public. I think that the true movie here is behind the whole "hacking" front. It is the development of characters the build up of a plot and an exciting climax and satisfying denouement. In closing, don't expect a command line prompt or a true UNIX client on any of the systems because it just doesn't happen in movies. Instead watch the movie because its exciting, fun and a great throwback to the early 90's.
