Well I haven't watched any more eps past ep1 of Strange & Norrell and instead went back to the book and have been reading for a few nights and just past where ep1 ended. A bit over a 100 pages in now. The main difference between the show adaptation is just the show interweaving Strange's story.
The book's grown on me and I am enjoying it, but I'm not a big fan of the huge blocky paragraphs of description prose with sometimes dialogue imbedded. Just reads slow and feels a bit like work.
I also started Sanderson's Stormlight Archives 4 - Rhythm of War and reading both at the same time it's just night and day difference in style. Sanderson writes short sentences that are pages mostly filled with dialogue, between dialogues are short descriptions or action, but the pages tend to be a bunch of single sentence or few sentence paragraphs and it just moves fast. Sanderson reminds me of a Stephen King, very straight-forward layman easy reading to focus on dialogue & plot.
Whereas in Strange/Norrell an entire big page may be one giant block paragraph and a giant block footnote below it. Fair enough for people that enjoy that type of writing. It's always given me School English class PTSD flashbacks, so never been into books written like that.
