I've only seen one episode of the UK version and I guess I was so used to the American version that I didn't care for it. I usually like British programs (Mr. Bean comes to mind).
Yes, I am missing The Office. Steve Carrell was on Regis and Kelly last week and said the episode they were going to film as the first one after the strike was one they had done a table read on right before the strike. Can't quite remember what he said it was about but he did say it was very funny even at the table read.
