I just don't enjoy his writing style at all. I only ended up doing a couple chapters and probably won't go back.
Maybe part of it is the translation, but it feels like a huge slog. The only translated series I can really think of that I really loved is Millennium (Lisbeth Salander/Girl with the Dragon Tattoo). I think translation can be a challenge, because you're trying not to vary from the author's intent, but different language choices in a book are made for different choices at different times, so even a really great translator can be constrained by the original work. It's hard to match both the flow and intent of native writing.
