I watched the first War of the Worlds and that was enough. If they wanted to create a Strong Female addition I'd rather her been Ogilvy's actual assistant because I couldn't care about the adulterous journalist (what did either woman see in him was my second thought) or his pregnant mistress and the long boring focus on their lives. The show really really wanted me to love them and hate the military as shown via Rupert Graves but I really didn't. The flashforward took any tension out of it for me, it'll be years of the war and Amy and her offspring survive.
I have a few memories of the film version (1953? Not the more recent one) and I'd take a USA setting over this UK setting with the focus on how "modern" it is with the Amy storyline. What's wrong with following the book more faithfully? The ABC Murders miniseries from the BBC felt the same, unnecessarily grimdark with a focus on sex and kinks, quite unlike the more faithful David Suchet adaptation.

Knives Out looks like a fun movie paying homage to and poking gentle fun at Christie genre :)
