It never ends, does it?

So, I was actually paying attention to a trailer for the new movie The Golden Compass and I've realized that it's yet another book turned into a movie. (The other most reasent book movie is The Seeker: The Dark Is Rising). For a society trying to get kids to read they sure are turning a lot of their reading material into movies. I think that's the worst thing they could do to books, it keeps people from reading them because it becomes:
I've seen the movie what more could there possibly be?
And that's just wrong, there's so much more to books that just doesn't fit into a two hour movie. My 8 year old sister refuses to read the Harry Potter series for two reasons 1-She thinks they're to long (She's 8, anything over 30 pages with out pictures is long to her.) 2-She's seen the movie and believes that she knows the whole story.
Back to my main complaint though, I loved The Dark Is Rising Sequence, it was a beautiful story over the span of 5 books. Even if there is a sequel to this Seeker movie I'm sure a lot of the story was lost and even more of it Hollywoodized. I'm sure they've destroyed it but I won't make the final call on that till I actually see it (I'll probubly just rent the DVD or something)
As for this new movie The Golden Compass I can already assure you they have the other 2 parts to this one in the works or possibly even finished and if they don't then it's just ridiculous to even bother with the first movie. I haven't yet finished reading this one but I do own the collection and I've been in the process of reading it for a couple months now (I haven't really had free time to read which has been really annoying). I don't like Nicole Kidman so I'm probubly never going to watch this movie so I'll never be able to say weather or not it was true enough to the book not to hate. Oh well.
