Mirai

The Good:

This movie has really good animation and soundtrack. It's beautiful all around, simply put it's a joy to look at.

The bad:

They main character, for me, was likeable. A lot of reviewers here hate him and to them I say: please refrain from having kids. He's just a young boy who is trying to adapt to life after his sister was born. He gets less attention and love from his parents and that's the main plot point of the movie. Because of this, he misbehaves and throws tantrums to get his parents' attention. His parents don't give a **** and so it gets worse. It's kinda painful to see a kid in this position, he is pretty much being ignored and vilified the entire movie.

The story then takes a supernatural turn, with time travel and other surreal aspects. The boy goes on journeys through time that are completely unexplained, his dog acquires a human form and all this to teach him a lesson and make him behave again. He gradually becomes a good kid throughout the movie for no apparent reason and learns to love his sister. This character development was poorly done and the supernatural parts were just confusing as hell, there's no explanation or exposition for ANYTHING, he goes on a travel through time then comes back and learns a lesson, rinse and repeat.

Overall the story was meh, but the animation was great. Also the voice actor (and dialogue writing) for the protagonist was beyond annoying.
