That's what I LOVED about T1 that none of the following movies even came close to capturing. Skynet had reduced humanity to the level of rats, scurrying around rubble under cover of darkness, living underground in filth, and eating the most disgusting-looking shit you can imagine. You could feel the desperation and utter despair and that humanity was on the absolute brink.
Fast-forward to, say, Terminator Salvation. Humanity is now living above ground right out in the open in broad daylight without a care in the world. Everyone looks healthy, well-fed, and is wearing make-up and has blindingly-white, perfect teeth. I'm sure the humans in Genisys will look even better.
Hell, I bet Kyle Reese won't even spend the entire movie running around in shit-encrusted, piss-stained old bum pants like in T1, either. Seriously, that was so gross that Sarah Connor fucked the dude after his balls were marinating in those foul pants for, like, two days. Ugh.
