Oh, right, I saw Terminator Salvation a couple of weeks ago; I forgot all about telling you. I kinda liked it, actually, and I think the key to that was walking in with low expectations after having seen lots of bad reviews. I didn't expect a masterpiece, and I didn't get one, but I got a pretty good war yarn.
It did strike me though - this is my main takeaway from the film, I keep thinking about this - those machines are really inept at the killing-mankind business. They go in mano a mano, shooting bullets, expending lots of energy, and they take human prisoners and whisk them away to their headquarters where they need to feed and take care of them, instead of just killing them. I get it from the storytelling standpoint, of course - this is so that the hero can make his way into enemy territory and bail out the hostages. But really - if I were a machine, and I wanted to kill off mankind? I wouldn't bother shooting them up, I would take their life support away - poison the water, burn the crops. (This occurred to me at the very beginning of the film. It starts off in a bleak, gray, deserted landscape, and when Christian Bale appeared in his fatigues and combat boots, my first thought was how well-muscled and well-fed he looked, and I was wondering where he'd get all those protein shakes needed to maintain his body.)
