I gave 'The Watch' a go last week
Apparently, BBC World made this without knowing a thing about the actual books it's supposed to be based on.
It's based - very, very loosely - on the characters in the 'Watch' strand of Terry Pratchett's Discworld books.
When I say 'very loosely', I mean the names and species are similar. That's it.
I gave the first episode ten minutes, and that, imho, was nine minutes thirty seconds too much.
To say it was hellish would be giving it an undeserved compliment.
Several years ago, Sky made three film length versions of STP's books, and Neil Gaimen's version of 'Good Omens' was a TV adaptation. These were in every way superior to the Beeb's offering.
