Running behind with these review so will try to catch up.
One of the biggest problems when your basic premise for a show is that your entire race has been virtually wiped out, is that there isn't much room for comedy. It doesn't matter if your show is sci-fi, drama, thriller or western, you need those light-hearted moments to help you relate to the people a little more.
With BSG, we are further hampered by the fact that each episode only progresses the story by a few days, so by episode 10 it we had only moved on about a month since the apocalypse. All of this might explain why the few comic moments have been isolated to Baltars continued descent into madness because of the voices in his head. Of course, this backfired in the recent 'Six Degrees of Separation', which was by far the worst offering yet from Ron Moores team.
However, with Tigh Me Up, we are offered a light-hearted look at the reasons behind Colonel Tighs destructive tendencies, as his alcoholic, bed-hopping wife returns from the dead. Of course, it's the b-story that really appeals as Adama, Roslin, Baltar and Tigh all get a serious case of paranoia over who could be cylons.
It's not polished, and some of the comedy feels forced, but this is common in first season runs. In the end the ep is a light-hearted look at McCarthyism and nothing much more. Number Six still grates me, but it's livable atm.
Tigh Me Up, Tigh Me Down: 6.5/10
