I think the only Star Trek
I like as much as SG1 is DS9. SG1 is just a nice, fun sci-fi series that doesn't take itself overly seriously. I absolutely grew to love Colonel O'Neill. Atlantis
was Ok, but it after a pretty good first season, it rarely did anything to make itself stand out. I know I'm in the minority, but I enjoyed SGU. I thought it was interesting and I appreciated that it tried to make its own name for itself. However, SG1 is still by far the best. I'm even one of the few who thought it bounced back quite nicely seasons 9 and 10 after a generally mediocre season 8.
