First of all, I do not know the books.
Saw this on prime, thought ok me, let's look.
Some parts of the movie are really well done.
The animations I like better than me.
Parts of the idea are super and classic for such films.
The music and sound effect are well distributed.
But what is not so good, is the acting and not fully thought out concept of history.
When I compare this here with Twilight, Twilight gets 100 points and the 77punkte here.
But GSD I do not compare it, because it's not the same :)
(I was going to have just mentioned!)
Unfortunately bring these two main characters the film something to case.
Therefore, only three out of five stars.
Recommended for fans and genre lovers :)
