more books into movies?

I read Extremely Loud and Incredibly Close this summer (mostly while on the metro in Barcelona). I really enjoyed it, and was very pleased with the ending.
I just found out about the movie, which will star Tom Hanks and Sandra Bullock. From the trailer (below) it looks pretty good, ever though it is not really how I imagined it in my mind.



Everything is Illuminated (by the same author) was made into a very good movie, so I think this should be good too. However, I hope that it keeps true to the book a little more, while still making sense.

Damn, why are almost all the 'blockbuster' movies, made in the last decade, so unoriginal? It is very disappointing that most million-dollar-movies are either remakes, sequels, or books (turned into screenplays). Maybe its a lack of innovation in the media, or maybe its just laziness, or even greed?
This is why I never go to the movie theaters any more (unless they are showing cheap indie movies or foreign films). damn, that makes me sound like a fucking hipster....
