I see these comments often in reviews. I just finished a light read by Lucy Diamond and it was described as "slow". It wasn't. It was 372 pages which I think is average. I'm one of those who likes a story to develop properly and I like a lot of detail. I see the Cormoran Strike books get criticised a lot for this - I know they are very very long - but it's necessary to the plot I feel. I like to know about characters, back stories, details - if it's done well.
Why do people want surface skimming stories that are disposable?
