It had awful pacing, No Worldbuilding, Protagonist was Insufferable, But his Dad was Even worse, Natsuko is a great character ruined by the fact that she just expects Mahito To call her Mom, and Mahito’s complete Shift in his attitude towards Natsuko was FF8 levels of unbelievable, and the ending was just so abrupt.
An otherwise painfully mediocre film saved by decent animation
