I went to catch this movie in Imax 3D with high anticipations, but was almost immediately disappointed when Kyle's monologue revealed that this film's plot does not follow the events of Salvation. Because all the previous Terminator films follow a single continuity, I feel not continuing from Salvation is a needless sacrifice, especially when the opportunity to do so comes at absolutely no compromise to the new movie's reboot plot and moreover when doing so could've contributed greater coherency to the reboot plot in that with each new reverse time traveling sequence, historical events are altered slightly, and thus a reboot would not seem as arbitrary, but rather necessary as the new timeline flows along a parabolic curve and not a circular arc. Instead, we have a separate timeline to start with which, given the 1997 date for Judgment Day, we can only speculate that it's the timeline prior to the first Terminator, but of course we're left with no explicable cause for it bypassing the first Terminator timeline and rebooting to Genesys, which is what happens, which in turn means that it can't be the timeline prior to the T1, which means it's just some arbitrary timeline that skews past the main timeline we've all been coaxed with.
So that's my gripe in a nutshell, but despite this totally avoidable ****up, I still found it very entertaining, with jokes and action sequences that any Terminator fan should be able to appreciate. I really have to give props to the CGI team, and to Schwarzenegger for being in that good of a shape for his age. I like how Pops had to face three different terminators in one movie, and him ending up as an Arnie T-1000, although this inadvertently creates tension for Arnold's aging appearance in sequels. I also appreciate the fact that the script-writer didn't just have Skynet taking control all over again, although this inevitably means that future films will feature pre-Judgment Day struggles--which of course was the intention all along.
Other things I don't understand are why they didn't simply reuse the same T1 footage for past timeline scenes and the nature of the Arnie T-1000 (along with the T-1000 in general). Was the creation of new footage due to copyright issue? The inconsistency I noticed but don't really care much about is when the T-1000 drops a part of himself into the relieved T-800 and reactivates it. As soon as I saw that, I had some subtle feeling of unfamiliarity but didn't come to full realization, or remembrance I should say, of the well-known fact that memetic polyalloy is incapable of forming "complex moving parts," only "knives, stabbing weapons." I mean, who can forget Arnie telling us in T2 that it simply "doesn't work that way." This, in turn, begs the question of whether the Arnie T-1000 is completely polyalloy or if it is an Endo-polyalloy mix...
I know I may be among a few for saying this, but I like Salvation. A lot. It has substance--again, due in part to continuity of timeline, which lends it an immediate level of precedence which the film's plot doesn't fail to deliver in my opinion. It's got a great theme which is supported by the entire cast, and at the end of it, I'm left wanting more. Of course, the inevitable question eventually comes up as to how far it leads until it reaches the defeat of the machines and the use of their time machine, and whether the story should completely end there. That's where Genesys steps up to the plate, but instead of a grand slam, we have a base hit that puts a new runner on but at the cost of having the runners put forth by the previous films irrevocably thrown out.
