Well, having now read what everyone said, I can see that what some of you found impactful, I found obnoxious. But, that's all good.
I agree with what most everyone has said so far, but will be interested to see what you think about my opinions.
In my mind it's hard to get past the time travel paradoxes (quantum physics or no). But, those aren't a big deal to me. I only know of one movie that actually effectively (in my mind) dealt with them--Millenium. Again, just attribute this to it being a mindless popcorn flick--which means, ignore plot holes.
I also disagree with some of you about T2 being better than Terminator. I would say different, rather than better. Terminator was a low-budget, nail bitting, action movie that helped propel its participants to stardome (granted they were mostly on their way). Its more gritty and down to earth. T2 is what happens when you get a budget. It looks sleeker and has funner special effects, but it loses that gritty edge. I personally care for the gritty edge over the sleek special effects, but I would ultimately just classify them as different--and both enjoyable, but for different reasons.
