Could have been amazing

Rating: 5/10 (10 October 2019)

The animation is enough to carry this film. It is truly quite amazing. But the film is a little flat and here's why:
1, Voice acting is monotone, forced and devoid of genuine emotion (except Seth Rogen).
2. Though the animation in general was amazing, there was a lack of emotion on the faces and in the eyes of the characters. It's a bit like those shows where it's real animal footage with human voices.
3. Lack of humour.
4. Music was a bit boring.
Could have been amazing with a bit more effort.
