I adore long books. I don't mind a languid pace or a large complex of plot threads or even digressions, provided the reading is engaging. If a story and a world are enticing to me, I want to spend as much time in it as possible. Many of my favorite books are very long, especially classics like Middlemarch, Vanity Fair, The Way We Live Now - all more than 300,000 words - but some of my modern favorites have similar word counts, like Neal Stephenson's Anathem. I've certainly slogged through some that were longer than they needed to be - the second time through Murakami's 1Q84 I noticed how repetitive it was, and I've been working on John Barth's The Sot-Weed Factor for a while now and have come close to giving up. But in general, I love long, expansive, immersive, detailed books. At least, I'd never shy away from a book based upon its word count alone.
