Good, but my favourite line of the whole show:
The Doctor: Oh, you are beautfiul! No really, you are - you're gorgeous. Look at that, space age clockwork. I love it, I've got chills. Listen seriously. I mean this from the heart - and by the way, count those - it would be a crime, it would be an act of vandlism to disassemble you ... but that won't stop me.
They do and I loved Catherine Tate as companion in this and series four, but it's not as good as The Christmas Invasion. Problems with The Runaway Bride include really annoying, overbearing incidental music at times and, for me, it didn't really have the sense of peril that you need if the whole human race is in jeopardy.
