Flow
As an animal lover, this made me feel moments of tension, fear, joy and sadness. So this movie is more like a wave that goes up and down and makes you go through every emotion with these characters.
There is nothing new I can say about it. It's even nominated for best animated film (which I hope it wins).
The idea and animation are unique and almost too realistic for an animated film today.
I love how they made the backgrounds look more realistic but used a different style for the animals. Creating a highlighting and interesting contrast.
