If you already like the Given anime series, then this is a nice extra to the little events after the series. This is largely focused on Akihiko x Haruki. If you only want the main couple, there's an OVA that focuses on them in the same timeline as this movie.
Review:
The innocent high school romance of the main couple is sweet, and give little butterflies flying around when I watched the main series. But this movie focuses on the adult love lives of Akihiko and Haruki, which is definitely more complicated and highlights the complexity of the human heart.
"All is fair, in Love and War" - John Lyly.
I interpret this quote as all is fair in Love and War, because nothing is fair, and getting hurt is almost inevitable in these situations (Whether is due to strong feelings or the circumstances that you are thrown in), thus it is fair in the sense that (almost )everyone is hurt.
There's so much more at stake for every decision we made as we grow older, and some struggle between ambition and love (Ugetsu), some struggle with love and envy for the same person (Akihiko), while others are lost in uncertainty and unrequited love (Haruki).
This story(and song within) reflects how it is so difficult to make a decision and let go, then believe that letting go is okay even though it hurts so badly, because the dawn will come again.
The flow of the story is smooth, and well paced. The movie though focuses on Akihiko x Haruki, it doesn't diminish the influence of the main character (Mafuyu). The characters in Given definitely are properly developed and appropriately focused to allow viewers to understand where they are coming from and how some situations progresses.
The animation is of standard slice of life quality, so not much to nitpick.
The song, definitely is the true highlight of Given, did not disappoint.
10/10 might be a little exaggerated, because I truly like the more complex and mature love story (yet not roundabout and infuriating) of Haru/Aki and this movie gave me the closure I need from the series.
Also the main series kind of hurt me with Mafuyu's dark past, and this movie is more "happy" as compared to that, hahaha.
