T1 is a loop movie. T2 opens the doors to multiple timelines but without crossing the line, and T3 crossed the line.
Here's how I see it:
Time can either be changed, or it can't. If it can't, then
T1 is a complete closed loop. Everything depicted was "original".
But if time
can be changed, then the events of
T1 were
not original. Which means that the accelerated Skynet developed from the Terminator's chip was not the original. Maybe the original always was a Cyberdyne project. But maybe not.
In a way, therefore,
T2 requires us to think that, unless the Connors find and destroy the original Skynet, the threat is still out there. (Unless only Dyson could invent Skynet, I guess, in which case his death
could ensure a peaceful future.)
I'm the first to admit that
T3 is not the equal of the first two movies. It's sort of like the brand-new
Rolling Stones single: unoriginal, and not as good as the classics... but, thanks in large part to the presence of its original star, still better than the vast majority of new stuff out there:
Ex:
"Doom and Gloom" > "Teenage Dream"
"Terminator 3" > Bayformers trilogy
... Now,
T4,
there's a movie with
nothing to offer!
