I also enjoyed the series, although there were a few things that grated on me just a little (I'll detail them below). On the whole it was great. I loved:
- Sheen and Tennant as Aziraphale and Crowley
- All of Episode 1
- Adam and The Them
- Gabriel, Hastur and Ligur
- The history of A&C in episode 3
- The costumes
- The music (incidental and Queen, and the variations played over the closing credits)
- Lots of little tidbits I'd forgotten were in the book.
- The ending (that's not in the book)
- The diversity of casting (genders and skin colour) for many of the smaller roles. It was, of course, a lot of white people in the main cast, but it *is* England...
What didn't sit so well with me was:
- Anathema being American - although I grew accustomed to it after a short while. It was just the initial shock and I think I'll be more accepting of it in future.
- Frances McDormand as God. Her voice is just too American for the part. I think the Narrator should have had an English (BBC) accent or something more neutral that McDormand, even if it was still American. Plus there was sometimes too much narration, some of it unnecessary - describing exactly what we could see on screen.
- Death's voice. Sorry, Brian Cox, but that wasn't how Death should sound. Christopher Lee got it right in the Discworld cartoons and The Colour of Magic. I know Good Omens Death isn't Discworld Death, but the voices should be similar.
- Death's look - those eye sockets were just a bit too creepy.
- The "signposts" used as on-screen titles. I didn't like those at all. Would have much preferred just the words as titles without the silly animated signpost.
I'll try and see if I can get over these things on the next rewatch, because I do think it was very much a wonderful show, but I have the mental images in my head of having read the book so many times over the past 30 years to try and shake off a bit.
As for my current opinion on the series i enjoyed it as much as I have the other dramatisations. I find that Terry's books port well onto video and with the right cast the humour can be just as funny.
Having been involved in Discworld theatre for a number of years, I can tell you that it works incredibly well on stage too - that way you can let the audience's imagination take care of the more complex special effects and just focus on the humour in the dialogue and action
