Ok, so I am giving it 4 stars because I loved the movie and the characters. Why I didn't give it 5 is because in my opinion Wolf Children was so much more emotional and just a bit better than Mirai. Don't get me wrong, I love Mirai but it didn't give me the goose bumps like Wolf Children.
I know people might see a lot of comments like this one and let me tell you this. Don't listen to what others say. If you think you'll like the movie, go on ahead and watch it! If you think it will be too boring for you then just don't. I am saying this because my step dad looks at reviews and if the movie has less than 3 (or 4) stars then he won't watch it. But the thing is that EVERYONE has their own opinion and just bc 3 or 5 people say it a bad movie doesn't mean you should not watch it.That's JUST THEIR opinion.
