Ok... few questions here, not sure if the answers even exist yet. However...
Are these meant as a reboot? Or does these follow one of the (several) preexisting Terminator continuities? Will this take place in the present (or near present), or will this be in the apocalyptic future? How fucking great it is to have Matt Smith in this movie?
Personally I think the best thing done with the Terminator franchise is still the first movie. The sequel was pretty good, but the kid in it gets real damn annoying. The third and forth films I could do without. The television series had some interesting ideas, but didn't do much with them, admittedly it was cut short by the network and may have been building toward something, but we will never really know.
You know, if I had to make a guess based on the VERY small amount that I've read about it thus far, The fact that we have John, Sarah, & Kyle and the title is "Genesis" sounds like they're going to be looping back into the existing continuity at some point, which would change things into a new continuity going forward.
As a brief overview of my feelings on Terminator:
• T2 was the first R-rated film I ever saw, when I was 6, so John Connor as a punk-ass early '90s kid just reminds me of the exact kind of kids I grew up with, and the T-1000 is still one of my favorite creations ever, and especially impressive technologically speaking.
• I saw Terminator a good while later, and really liked the theme of time travel behind it with Kyle & Sarah in a seeming bootstrap paradox and the fact that it's a lot more of a horror film.
• T3 is the weakest, but it started to address the inevitability of Skynet's apocalypse and Skynet more aggressively going into the past and the Resistance's tactics are known and that because of that, it is building anti-Terminator units.
• Salvation is one where
(probably because I got to ask the director a question about how Time Travel functions in the film) I really like what was done with it (and it also shows off a lot of the cool stuff that was done in TSCC but cut off early).
Salvation is the first time we get an insight into the fact that Skynet keeps learning from how it doesn't succeed in various timelines, and that - so long as it sends something back - it keeps staying alive to fight another day, and changes its tactics based on that knowledge. It paints the picture that every. single. victory against Skynet is meaningless if it sends anything back in time, because it just splinters off another timeline where it can save itself. (Unlike some series like Looper, it doesn't overwrite a single continuity, but just keeps shifting into another branch, and all it needs is to win ONE of those - because that final branch is always the timeline we actively follow). TSCC demonstrates that in much greater detail.
The fact that it's planned as a trilogy means that I think that they're playing a long game with what's happening, and I'd be interested in seeing the idea of them actually trying to shut out Skynet from being able to develop time travel after the apocalypse. I think that starting things in a more "modern" pre-apocalypse time in a necessity. Personally, I've always thought it'd be rad to see them doing things in the past, and occasionally jumping forward into the current apocalypse that changes slightly (i.e. would be a different timeline each time we jumped forward to it), as they affect certain points in the past - but that's cause I'm a BIG time travel junkie.
tl;dr - There's no sense in a reboot with a multi-branching time travel series, so I'd bet that they jump in somewhere and start a timeline continuity specific to the film (since that happens in Terminator every time someone/something travels back). I'd guess that it happens in Sarah & Kyle's early timeline, and then moves into the apocalypse later on.
Also - still endlessly happy about Matt Smith being in this.
EDIT: High five to Gabe for also loving Salvation.

they had a good ball rolling with Salvation. Ffs I wanted some future battles already instead of time travelling all over again.
. What is it, a 90's TV show?
