I was never bothered by the terminator, really. I was too enraptured by all the events going on and trying to make the right choices to get my crew through it all.
I did have to smile to have it's weak points labeled as such. Seeing people get liquefied to goo was particularly gruesome, especially to think how it's been visually hinted and in dialog itself that they made a huge milkshake out of hundreds of thousands of innocent civilians for their pet project. Hints at what some/all of those Reapers represent, and how much potential data on destroyed species is lost after you kill a Reaper. Wonder if you can collect data such as history, memory, technology from the DNA of another species though...seems like a decent plot point.
