I liked Blink a lot - but I didn't write it up because I was out when it aired and didn't get to see it for a while, so I thought it was a bit late!
I can't remember the girl's name either :)

They seem to do an episode per season where the Doc is almost 'incidental' - sometimes they work, like this one, and sometimes they don't, like the one last season with Marc Warren and Peter Kay. (Which I liked for the quirkiness, and Warren was great, but it wasn't a great ep.)

So now you're up to the final 3 - which are fantastic - enjoy!
