A review described it as based a story written by a 19 year old with a screenplay written by a 12 year old.
The critic was spot on.
First, I understand that to shove a 400+ page book into 2 hours you have to abbreviate so I forgive that, but they changed major elements of the plot that could have been left alone for no particular reason (although perhaps there is some political sub-text that I was choosing to ignore). In any event, the acting is poor, the dialogue is poor, the plot has been butchered and left to bleed to death by the roadside. The dragon effects were fantastic, but not since Jurrasic Park has this saved a movie. I will say, the styling seemed a lot like what Chronopia would look like in a live action movie.
I read the book. I liked the book. I am attempting to brain dump the movie.
Learn from my pain people.
