So I FINALLY read Good Omens. It's only taken me 20-odd years to get round to it. 
 And I think my experience of it suffered from all that build-up. From everything I've heard about it from many readers who love it, I was expected the book to make more of an impact on me. Unfortunately it just kept reminding me how much I love the Discworld series and would love to re-read all of those books (again). Or how brilliantly weird The Ocean at the End of the Lane is. 
 That's not to say I didn't enjoy Good Omens or think it was great - I did! I particularly liked all the sections featuring the four horsemen, for example. I just don't think this is Pratchett or Gaiman's best book.
