I really enjoy reading all of the various viewpoints on this thread. I watch Sarah Connor, but I'm ambivalent about the show, and it's interesting to see why so many others are too.
I agree that there is a lack of urgency, that the missions aren't as clear or easily resolved as they were in Season 1. For me, I started to lose interest in the Season 2 opener. I knew that Cameron wasn't going to kill John, and it was a wasted hour or so. Particularly since Cameron was stalking him at such a plodding pace. At the least I wish they could've sped up the chase and had more action. I also thought the T-1000's reveal could've been held off until November sweeps or the season finale.
There are just too many Terminators in the past. Why not just have Skynet go back and kill Sarah Connor as a kid, or her parents, grandparents, great grandparents, etc. if it can send Termintors back into at least the 1920s?
I'm not as big a fan of Cromartie as many on this board are. I think he's adequate, but he doesn't exude any real sense of menace, not like the movie Terminators. And he's been on far too long. Too much of this series has become a long chase sequence. For a two hour movie, that works, but you can't sustain that for a season or an entire series. The T-1000 is more interesting, she exhibits a bit of a personality, but I think making her a Terminator was unnecessary. Also, if they're going to do Terminators of the week, mix it up. There should be elderly Terminators, Terminators of every race, creed, and age.
I think this show needs more human villians, government and corporate. Keep making it harder to pull the trigger. It's easy to blow up a machine, not so easy to do the same thing to a human, like Miles Dyson. I also think it was a mistake for Ellison to catch on so quick. Keeping him a dogged FBI agent out to get them would've added more tension to the show.
I think the cast is pretty good though. Dekker is a bit too whiny, but Headly, Glau, and Green are very good. I think Riley is all right, and I liked her twist. Jacobsen is a welcome addition to the cast too.
