This movie is more of a breather than an actual plot backstory but it is still good because it let's you appreciate the characters more.I personally enjoy movies than they show unrelated plot moments of charaters I like.So ,if you are into that as well then you will like this movie.As of the artstyle and sound,it's excactly the same as the anime of course.Overall,I highly recommend i,if you are into Re Zero's characters and want to see a fun,plot-unrelated story.Also,the movie is between two episodes in the first season so have that in mind if you want to watch everything chronologically.
