I've watched the movie first before reading the light novel. It's been a very great experience. Both movie and novel complete each other. This is just as i've expected. As the novel deepens at the characters' mind which is the movie can't really show. It also a well-translated one, as beautiful as Shinkai's words. I recommend this book to all the movie fans. It's kinda pricey for a thin book but I think it's worth it.
