If you love Battlestar Galactica, you will have a blast watching this, its most likely predecessor.
SAAB isn't really about aliens, or about action in space, or anything that is so easily related to "TV Sci-fi". It is about the drama of war; its effect on people, on both personal and larger levels. It's about reality, really. And, given that the series comes from the mid-90's, this is truly quite a remarkable feat. The special effects still live up to our expectations (especially after the first 5 or 6 episodes), and the characters truly, and I mean that, truly grown on you.
It's really interesting to see this show now, in a post 9/11 world. Again, way ahead of its time. You will know what I mean when you see it. ;)
A rare treat from a long, long time ago...
