It was War Stories. I really liked the premise and most of the episode, but there was something about it, plus the aforementioned over-use of the Chinese swearing "gag." But like I said, I didn't dislike the episode, there was just something about the writing which, at the time, struck me as not as good as previous episodes. I don't know, maybe I was in a weird mood.

So far, I think my favorite has been Shindig or Out of Gas. I'm really looking forward to Jaynestown, though (I read the premise). I've been quite pleasantly surprised by Adam Baldwin. He's very good, and his character is really well written.
