Glad you like it! Actually, there’s one more episode with a Slitheen, “Boom Town”. But don’t worry, there aren’t any fart jokes, and it’s got a little bit of emotional heft. Won’t spoil it for you, but it’s pretty good. Plus it has Captain Jack.
I was unclear in my previous post. Boom Town is the one I’m watching next, and I figured out it had the woman Slitheen from the previews. I’m very glad to hear it’s not as annoying as the previous episode as I wasn’t really looking forward to it. Will watch it tonight.
I still wonder at their decision to call the girl companion “Rani” when one of the classic enemies of the Doctor is “the Rani”. And if they’re doing that, the boy companion should be “Drax” or “Davros” or some other villain name to match.
