If you finished the anime and you’re caught up with the manga, you’ll definitely enjoy the movie. I personally think they did a great job choosing the actors, because it was wonderful to see our beloved characters come to life. A lot of stuff that we get to see in the movie, are stuff that happened in the anime/manga.
The ending, isn’t something I wanted or was thrilled about. But it was cute nonetheless. I understand since it’s a movie, they can’t fit in absolutely everything, they had to come up with something.
Do I recommend the movie? Absolutely.
I just think the ending is something not everybody will like. Then again, YOU might absolutely love it. Find out for yourself :)
