Neil Gaiman had one rule for the Good Omens adaptation: making Terry Pratchett happy The devil is in the detail of Amazon's long-awaited Good Omens
Personally, I like the escape from the Donnager in CQB. The music, the camerawork, the Zero G scenes were all amazingly done.
I've read the books up until Cibola Burn, so my impression comes from comparing my experience watching the story to reading it as told in print.
Season 3 was incredibly rushed through and little of any character's motivations or thought are clarified as they still make more or less the same decisions. Two noteworthy characters (Pa, Bull) combined into one character (Drummer) whose actress only does one vocal and facial expression, which I happen to mirror every time she gets air time.
Show Ashford, an arguably much more sensible and intelligent man than Book Ashford, is unreasonably suddenly deemed necessary to reflect Book Ashford without any clear change in motivation.
So many things are done weirdly on the show that didn't need be done. Those are a few examples off the top of my head. What do you think?
