I acquired Seasons 1 - 4 last year and have been watching them too and am currently in Season 3. I just read through this thread. Very cool.
I am not sure if there were spoilers present or not. I have read some of the books published since 2005 or thereabouts in the multiverse. Look forward to watching the rest of the series.
Thanks also for the suggestion of watching "Continuum" but I do not watch TV and am wondering if it is a TV series. I did watch the SG movie with that title already.
Maybe sometime I can start reading the ENT novels. I wonder if they take place during the series or after the series or both.
