This is an extremely amazing film. But sadly it requires someone with a brian to actually understand.
It delivers an amazing hand drawn beginning to the movie which helps the viewers understand and then the cgi animation after that is also absolutely amazing.
People need to realise PG13 means it’s not recommended for kids under 13. If you still insist on bringing any kids, it’s sadly not the movie’s fault.
The plot twists in the movie are unexpected and requires a lot of thinking for viewers, so people expecting a thoughtless movie that you can just watch, save yourself the trouble.
