For those who didn't like this film due to some corny lines, continuity errors and such, I have found a fanedit that is simply amazing.

The person who made this fanedit has really done a tremendous job, cutting items that didn't work, improving the way the T-850 interacts and behaves and cleaning up some of the cheesiness.
This movie was improved a hundred-fold. All of the cuts worked brilliantly, making the T-850 much more machine-like in its behavior and making the activation of Skynet much more plausible. (Note, pay attention to the screen when the T-X is getting the information on its targets after stealing the car. It's important and you may miss it). It now holds basically true to what we've learned about Skynet's activation previously and some continuity has been restored. If I hadn't seen the film previously, the scene of Scott killing the police officer would have been a much greater surprise, and it's certainly more appreciated than the original version. Scott's talking to the cops when answering the door was horrible in the original version. It didn't play right, he didn;t sound sincere at all and experienced cops would be able to tell that. Now we know nothing about it and suddenly WHAM. Excellent.
However, my favorite part of this edit was the ending. By removing the V/O and using an alternate music track, the editor made it a much more powerful and emotional ending. The camera pulls back from John and Kate with the strains of the music playing, and we see Skynet launching its attack upon the world. We hear nothing but the music and the faint sounds of destruction. It builds until the final fade out. It's always struck me as an emotional scene, and this edit has made it so. It's sad. It's gut-wrenching. It silences you. And it's a perfect ending.
If you have a DVD burner and a good connection, get this edit. You won't regret it at all.
