I watched the first one last night, massive fan of both Pratchett and gaiman but the humour felt a little forced at times, overall though I enjoyed it.
I read the book multiple times years ago - there are differences. (trying not to spoil it)
Sheen and Tennant do a great job of Aziraphale and Crowley.
Just finished it.
Swapping Pestilence for Pollution was an odd choice too. Even more so given the bit in the airbase where they say something along the lines of "First there's War. Then comes Famine. Then Pollution takes over". Surely pollution would subside after war and famine, rather than increase? Disease, on the other hand, would rise. It's like they wrote the scene with Pestilence, then swapped him out for Pollution afterward...
I'm pretty sure that's how it is in the book with the swap, pretty much word for word.
Will need to read it again now.
