I used to enjoy books dramatised for television, but over the last few years I have gone right off them.
The main reason is that production companies consider that audiences cannot handle the books as they are; they revamp the characters to make them more modern, they change the plots to make them more 'relevant'.
I thoroughly enjoyed Joan Hickson as Miss Marple. She matched the character portayed in the books. Then the Geraldine McEwan version came out. Not only was she not the Miss Marple of the books but in the first couple of episodes I saw, the plots were tweaked to be other than as written. In one case a straight forward murder was made a lesbian triangle crime. A theme not in the book. At that point I stopped watching
The same thing has happened with classical series. I started to watch a dramatisation of Mrs Gaskell's North & South, but gave up somewhere in the first episode when the male lead was portrayed as tall, dark, handsome and young, everything the book character is not, which is key to the story. DD saw it out to the end but said what was meant to be the dramatic romantic denoument, set on a railway station (not as in the book) was so ridiculous and out of period she ended up laughing.
