Regarding True Blood, I enjoyed the series, but haven't read the books yet. When I do, I expect they'll be a lot different to the series, which I think might have had extra sex and gore crowbarred in to up the viewing figures.

Regarding Blackadder - I've watched series 2, 3, and 4 so many times I could almost quote some of them word for word now. Not so fond of series one (it's not bad, but it's not as funny as the others IMO)
