On one hand, I love that the technology exists so that people can do this. Really cool. And watching the 5 minute preview, I feel like this was done pretty well and will probably watch the 3 hour version. On the other hand, who goes to a movie that was based on the book expecting to actually watch the book? That never happens! Books and movies are different media. I never go to a movie expecting it to be the same. I expect it to be "based on" and nothing more. I'm rarely disappointed.
