Book vs Movie

Is the book always better than the movie? Are there any exceptions?

When I first saw this question, my reaction was to say yes: the book is always better and no: there are no exceptions. But I would have been wrong.
Last night, I watched The Chronicles of Narnia: Voyage of the Dawn Treader. And it hit me.. these movies are WAYYY better than the books.

That is quite the exception. The stories are good, don't get me wrong, but C.S. Lewis was a very dry writer. Not only that, but the stories are fairly short as well. Somehow, 2 hour movies have been created with all the wonder and fantasy and detail the stories just don't compare to.
And while the HBO show Game of Thrones is a show and not a movie, it's pretty awesome and very well done and I don't think the books are any better or worse. The book and the show is about even.

When it comes to fantasy and sci-fi, I think shows and movies can be better or about the same because you are able to relax and enjoy the images presented, some of which are so out there, it's difficult to imagine while reading.

Music

Can you get work done while music is playing?
For some reason, I am able to tune out audio. I can read a book while the tv is on or music is playing because I literally ignore every bit of it. I discovered how powerful that was when my friend sent me the Harry Potter audiobooks and I popped in the disc and checked my email. Had absolutely NO idea what the narrator said. I ended up having to follow along in my books because as soon as I got up to do something or even looked down at my nails or just sat there, I wasn't listening.
At the same time, when I'm working in the bookstore, I find myself singing along to music or I'll get off of work and discover that a song is stuck in my head that I didn't realize I'd heard.
I think music sticks with me more than any other kind of audio. But I can still tune it out if my brain is trying to focus on something I'm reading. I guess I'm just more of a visual person, so whatever I'm doing visually takes precedence over what I'm hearing.

reading

Do you feel obligated to finish all books you start reading?
Yes. I can only recall putting one book down halfway through because I thought it was terrible. It's important to me to finish what I start, even if I end up not enjoying it.
