Conventional wisdom would say that tie-ins are rushed and/or have to stick to a script, thus limiting the writer's imagination and sometimes forcing them to stick to the script, which can be bland for most writers. I was wondering are there any books based on a film out there that truly stand out? I'm thinking particularly fantasy or horror but I'd also like to hear about any author who's pulled off a great novelization. Has there's ever been a best-selling novelization? Have you ever read one you think was "high art"?
