Oh I too loved the T-X model Terminator concept - I just felt that the movie and it's execution as a whole was a dismal failure.
(Kristana Loken is freakin' Hawt!)
The ending was purely done that way to extend the possiblity of a sequel, which was in a way good because that gave us Salvation, which is leaps and bounds better than T3, but personally I prefer T2's ending and moniker:
"There is no fate, but what we make" - A better lesson than "Must milk franchise at all costs", IMO.![]()
