I LOVED both Terminator movies (haven't been up to seeing T3 yet, it looked like it'd blow). T2 is probably one of my favourite action movies of all time. Yes, I *am* easy to please, now that you mention it.
I coincidentally spent the entire weekend watching The Sarah Connor Chronicles series 1 (my hubby and me were looking for a series we hadn't watched yet and presto, SCC it was), and I liked it well enough. The only thing that drove me crazy was: Why the HELL do they keep shooting the metal with guns? Seriously, dudes, the guns don't harm them, come up with a new plan. Totin a whole arsenal with you as you flee the machines is just pointless if the bullets do no harm, no?
Plus, the time travel thing is just weird. I mean, there's John, aged 16 or so, watching his 5 year old dad! TOO freaky, seriously. I also took exception to some time-space dilemma's with the time-travel thing; some real paradox type things that bugged me, but I can't name any of them right this moment.
I have to say, since it's literally been years since I (and most people) watched the first 2 movies, nothing about the canon bothered me. I took the date-shift of Judgement day as a delay caused by the death of that Miles Davies guy, and Skynet having to be founded by someone else now, but like I said, I'm very easy to please about stuff like this.
Oh, and Summer? Love her. Would see anything with her in it. She's incredible, and it's really gratifying seeing this rail-thin little slip of a girl throwing big strong mean machines around like so many rag dolls. Great stuff.
