I have to admit: I never liked the franchise. I was dragged to T2 by my friends when it came out, and I completely ignored T3 until a year or so ago when I grabbed it on the DVR (and, boy, was that bad).
So I wasn't willing to give T:SCC a chance until (of all things) my wife wanted to watch it. And, damn, it was good!
After RTFA, I can agree: There were no concessions for new viewers. It's work to talk up a series to a bunch of friends or co-workers and then expect them to jump in. Even BSG had the (regular) catch-up specials that could be streamed or downloaded for free (I found myself regularly referring friends to those). T:SCC had nothing like that.
But, it had style. And it had substance. And, as someone who has watched every damn episode again in the past few months, I can tell you that there was a clear plot line and a clear view of where the story was going.
If you were too impatient to allow the story to be told, or have a hard time allowing for plot lines to unravel, then I suspect that most science fiction on TV isn't for you. If you enjoy a bit of philosophy and psychology (which IS a science, folks) mixed in with robot babes fighting each other in an elevator, then I suggest hunting down the complete series box set when it (inevitably) comes out. Maybe enough disc sales will prompt Warner Bros (who own the series) to do something more with it.
