It was a truly entertaining movie. I do believe that the
backstory of the male protagonist could have been fleshed out a bit more, but I
think, given the length of the movie, that it was exceptionally
well-structured. The characters felt fitting for their roles and actions, and
there were a great deal of funny moments and not-so-subtle references (the
protagonists of 「君の名は」made
an appearance, for example). I really did enjoy the overall dynamic of the cast. Nagi, the female protagonist's younger brother in the picture below, was honestly a highlight of any scene that he was in, especially if it involved his strange ability to attract girls his age.
Aside from the various sentiments expressed and parts of
conversations that I understood, I had a stronger appreciation of the location
(Tokyo) and certain plot points because of my prior knowledge of specific
things in Japan. For example, when the presence of a gun became relevant to the
story, I understood how and why it would elicit the particular reactions and
ramifications that it did. In fact, I was rather surprised myself when it
appeared. There were also other little things that likely made sense to me because of prior exposure. To be entirely honest, I kind of missed Japan a bit after seeing certain places that I had the pleasure of visiting last summer. Regardless, the movie was well worth watching in my opinion.
