this may just be me, but i have a kind of different view on things. yes, when you read the novelization its a massive spoiler, but just because you know the story, it doesnt mean that you know exactly what you're going to get in the final film. you have to remember that the novelization is based on the first draft of the script, and that there are elements from that draft that ultimately don't make it into the finished product. for instance, in the Spider-Man 2 novel Doc Ock's tentacles actually dialogued with him in his mind. they chose not to do that in the final film, a pretty good decision but it would have been interesting in that first scene with Ock in the warf when he says that he hears something talking in his head to actually have heard these hissy, whispery type voices talking to him.
also, in the Batman Begins novelization, the scene where Batman interrogates Flass is much less intense than in the movie, a good example that the novelization differs from the final film in a few ways that you don't expect.
but of course, thats just me
