This is a really great film, reading some of the reviews I think some of you need to rewatch this film as you've kinda missed half the plot or miss saw things.
Also this film is made with Pearl Studio, and co writing this was Glen Keane, a reason why it comes off like it could of been a Disney film.
Some people are criticising the logic of the film, which...I don't know what films you've been watching but please tell me an animated film where there is no magic and twist in logic. I mean c'mon, that's the whole point of it being animated.
Honestly I really love this film, the emotion in this is great it's a story of two souls dealing with grief.
For me it really hits home.
Amazing film, give it a try.
