I gave this a high score overall due to the incredible animation, character development and soundtrack. However, I do not recommend watching this if you are expecting a fluffy romantic film as you will be somewhat disappointed.
REMEMEBER this is part 1 of 2 and the cliff hanger left at the end of this was pretty intense. It left me feeling dejected and a little depressed. The cliff hanger leaves you on a sad note which made me not want to watch the sequel as I had a feeling it would also be pretty sad.
Other than the film being sad it has some amazing animation and an amazing sound track. The voice actors also portray the characters well and the character development through the film was intense but amazing.
