The T-X suffered a lot from being rationalized AS a female instead of as a machine that could assume either gender appearance but was entirely neuter-neutral (primary fighting form for instance would have been far more effective if it had simply gone 'Silver Surfer pure concentration' mode) itself.
The whole busines with raising her hand to an awkward (off camera prosthesis-screaming) angle to do the Swiss Army Knife bit was also...unfortunate.
Largely because the Dremel Tool saw blade was silly and the flame thrower alternate both impractical (where's the fuel) and absolutely worthless (zero ranged effect) in comparison with the blaster cannon that came before.
Again these 'delicate girlie toy' things, the extended activation time by which they are activated and the fact that they are not in BOTH hands makes T-X seem, prissy.
T-X doesn't run noteably faster than a T-800 and may actually be slower than a T-1000. Indeed the _length_ of it's stride is still entirely human which is flat out wrong for high speed motion of a heavyweight machine which should be loping (like an ostrich) or ungulate-bounding like a bipedal equivalent to a leopard.
If a T-800 wanted to peel off a car roof, it would simply slam it's hand through and pull in about 3 seconds (even though the flesh would be badly bruised, something less of a problem for mimetic-alloy T-X).
Also, the whole femnazi severe pullback on the bun hairdo, combined with the Red Klingon style of leather-me-up dress was simply WRONG for the T-X's /infiltrator/ role. The give an impression of overt aggression and barely controlled physicality which would NOT be how a female assassin would choose to portray herself in OUR world.
Indeed T-X's first few moments on the planet with the long curly hair and the little-girl soft expression would make her both more capable and VASTLY more terrifying as a betrayer-slayer from the male protectivist standpoint.
What will almost undoubtedly determine the T-X (and indeed even more so Aging Arnies T-800) validity during any followon sequel will be CLEAN (sharp depth of detail and seamless scene blending) digital renders so that you can, for instance, go to a true genderless ID rendering for multiple character shifts away from the 'base actor' as well as things like 'gunports' which fast-open provide for the Terminator to use weapons as we would, in an immediate-reaction sense of _combat_ rather than staged=standing-there idiotic duels.
As for the T-1000, if you've read the novellization of T2, Skynet had only enough of the mimetic glop to make ONE such prototype and it was also frankly 'uncertain' (scared) itself of what the multiprocessing and thus entirely too 'independent' 1000 series might end up evolving to.
Self-cognition could lead to a mental state that did not acknowledge loyalty to a higher cause for instance.
While I would agree that the T-1000 is a more rational carryon from the T-X (which is in fact labelled a T-900 in the T3 fan comic now in most grocery store magazine aisles) and thus perhaps better portrayed as being what we would 'finally, The Future!' encounter in the Skynet Wars themselves, the fact remains that the overall /concept/ of Terminator:Human conflict needs to be _vastly upgraded_.
For the sad reality behind ALL the Terminator flicks is that /nothing/ of the hand weapons used on each subsequent 'better model' cyborg could truly damage or even significantl /slow/ the creatures and thus humanity 'carries on' through what amounts to endless circumstantial modifiers and _sheer dumb luck_.
I put a large part of this down to the slow ponderousness of the Terminators 'action mode' physical displays but, the notion that the use of deliberate ambush rather than meeting engagements and super high powered 'effect' weapons (heat, electricity, explosive blast, cold) simply doesn't seem to occur to the oh-so-smart monkeys /either/ is not terribly complimentary to us hairless apes either.
Again this MUST change towards a more fluid, lightning quick (Alien and Predator themes), INTENSE combat where true attrition (speed of light plasma weapons rather than dorky Estes Rockets etc.) of BOTH forces is what makes static ambushes and force-on-force (numbers leveraging) engagement decisions still uncertain.
For the fact is, humans will always suffer from 'morale factor' indecision on building losses but a single Terminator that 'stood up and was reckoned' could charge it's way past a fixed envelopement and begin to roll it up from outside with awesome 40mph + on the fly targeting precision.
And such topsy-turvey unit combat resolutions are what is missing in gaining a proper evaluation of 'who is better'. And the drama of why.
Saberist.
