This mostly just seems to be leaning in on the advancements about tactics for the, "living tissue & mimetic polyalloy needed for time-traveling technology" and how both sides are advancing based on those rules – humans equipping themselves with more sub-dermal cybernetics, with the two Terminators working in tandem as a combined, but also divisible team unit of an endoskeleton entity and an liquid metal entity.
I do feel like it's worth mentioning that the
Terminator Genisys version of the T-1000 is still the one that feels the most screen accurate to the way I've always felt that the original Liquid Metal Mimetic Polyalloy material seemed like it ought to behave. The original T-1000 in
T2: Judgement Day always felt like it sat somewhere in the range between clay and putty in how it had a natural viscosity. The outer layer of the T-X from
T3: Rise of the Machines, felt like it was too mercurial in how it would bead up into tiny bits. By contrast the T-3000 in
Genisys was very much more a cloud of nanomachines, and not just a chunk of material.
This new, darker liquid metal Terminator feels like it's somewhere between the T-1000's Liquid Metal, and the T-3000's Nanomachines. While that's interesting from a technical standpoint, I think that the scenes that have been shown with it so far run into this weird area where – especially because it's just an outer layer – it feels like all of the liquid movements lack a degree of weight that the other Terminators have had. It's odd because the effect really feels off because it doesn't seem to have the substance it seems like it ought to – but if it's really a mid-point between those types of tech, it would likely have that kind of odd appearance to it.
I dunno, it'll be interesting to see if they get something that's more of a trailer (but hopefully not one that fucks the entire plot of the film like last time)
