T3 is incorrect in many places. I think we as fans want these corrections corrected! The question is, can we get an improved T3? Well maybe we should somehow get our message across to the big man himself, Schwarzenegger! I might be living in a dream world, but Arnold is a man who listens to his fans and maybe this might be the way. Maybe I'm talking a lot of s**t, but I don't mind :P
I dunno, all I'm saying is that an improved T3 would be a dream come true! Not just for me, but to you fellow Terminator fans!
As I've said countless times T2 is also inconsistent with the original in many places. If they redid the dialouge in T3 and Terminator said "CRS 101, T800" instead of "T-101" and John said "10" instead of "13" T3 would not suddenly be a fantastic movie.
The way to make T3 better is to give it the same depth as the first two movies, which I don't think you can do. You can't just inject depth into a superficial script. The script has to be written around an excellent story to begin with.
Could they have improved T3 for a DVD release? Yes. Should they now? Not really. The movie is what it is. Too bad it couldn't be more, but it also could have been much much worse.
