I read the book before seeing the movie and of course, I liked the book better, but the movie was actually really good.
yeah the book is indeed better like most books usually are compare to their movie counterpart. but i enjoy both.
I thought the concept of this film was very appealing, but, IMO it lacked something. It left me wanting a bit more, I don't know exactly what I mean by this, but yeah, i thought it was good but the story could have been developed in a a different way.
