For the record, I hate the !@&*%) Slitheen. Seriously, worst monsters ever. I was really hoping I'd never have to see them again. But on the other hand, Lis Sladen is just that fab, so I gritted my teeth and watched.

And, you know, it wasn't that bad. In fact, I liked it better than the previous story.

( Vaguely spoilery observations, though of a character rather than plot kind... )

And cryptile has already said pretty much everything else I might be tempted to say.
