BSG came quite a few years later (assuming you do mean the remake?).

There were other gems around that time though. I was chatting to friends about the Outer Limits just yesterday. Plus let’s not forget the other Star Trek franchise; Voyager.

I also love(d) Stargate SG1 (this was a little later too IIRC but much closer in time frame than BSG).

There were some pretty weird shows too. Some people liked Fargate. I personally couldn’t get into that particular show. But I did enjoy Lexx.

Edit: a little later (possibly around the time of BSG), but Firefly and Dollhouse shouldn’t be forgotten either.
