I just finished watching the secret world of Arrietty. It is beautifully made, very detailed and with a great soundtrack to back it up. It's a very enjoyable movie and it's great to watch how the borrowers manage to travel inside the walls.
Yet I feel like it's missing something. That magic spark when something unexpected or truly fantastical happens. I would have love to have seen something of Spiller's world.
Whisper of the heart is completely rooted in reality, but somehow that also had a bigger emotional impact on me. It's still a great movie to watch, certainly better then the average animated movie.
