Oh, this episode was hilarious from start to finish.

I think it was the single most well-integrated story in terms of the comedy. Nothing seemed forced, for a change. I knew that the Blue Guy would have to show up eventually, and I figured it would be kind of a drag, but this just cracked me up-- apparently these Blue People are descended from Bonobo-like primates. "It's considered impolite to refuse sex."

The character of the Blue Guy was quite well done-- just kind of easygoing, taking his effect on people for granted, and helping out in the end when he realized he had caused a problem. Where I had once dreaded his appearance, I'm now kind of hoping he'll come back. Excuse me while I go pluck my eyebrows.
And Claire and Yaphit having sex-- that was a sight to see.

That actually didn't quite work out how I expected or wanted. I figured that Claire's brush with death would make him realize how he really felt and he'd change his approach. And maybe that's what happened and they just didn't say so. In any case, the cool thing is that he is sincere and I wonder how this encounter might change their dynamic in the future. It was be interesting to see an inter-species romance where one party is non-humanoid. Also, I like sexy Claire-- she's just as hot as she was on DS9.
I also like how Kitan really rose to the occasion when both of the top officers (and CMO) were compromised. And it wasn't the first time, either. Ostensibly, it was Bortus who was in command, but she was the one who put everything together and took charge.
Also, we once again had some really cool alien races hanging around. Once again this show out-does post-TOS Trek in the exotica department. This show really looks futuristic and like a Space Opera should.
And it was nice to see Victor Garber again, but I hope he gets a more meaty part before the end of the season.
