I never really got in to SG1 as it was on when I was working and I was always missing it and it didn't really click with me.
Maybe I should give it another go because being a Farscape (known as Fire Escape in Chateau Bingowings) fan the later episodes have intrigued me.
With BSG I watched the miniseries, thought that was OK but didn't follow it up until much later.
As soon as I saw the first episode proper I was hooked.
I'm highly miffed that it looks like Caprica is going to be axed as I was really getting into it (probably more than I got into BSG).
