I started watching this with the short series in mind that is loosely connected to this and left a good impression on me.
Started a little disappointed with the actor choices but was pleasently surprised by their performance. Especially Shun's actor left a good impression, silent as he was most of the time. Nagisa's actor was another story. He had scenes that felt off amd awkward but also made me cry twice with his raw intensity.
The few intimate scenes and kisses felt real and were not awkward at all, the chemistry seemed very good and credible.

That said, Shun and Nagisa's lovestory is beautiful but not deeply explored in this and that's what I'm missing here...I would have loved flashbacks to the beginning phase of their relationship.
We are thrown into their broken relationship right from the start and I had trouble relating to Shun's still existing love for selfish baka Nagisa who just up and left for - what? A surf career? Wtf?!
Make this a drama instead, explore the depth of feeling, existential crisis of being gay in backwards Japan (sorry, they're still homophobic af) and a rekindling of their love and I'd be overjoyed...
As it is, it is still an emotional rollercoaster of a movie, family scenes are cute and hopeful, court and 'mum' scenes made me angry. In the end we are left with a realistic outcome that isn't satisfying at all (to me) and reminds me of the heartbreak of "Close-knit".

I cried quite a few times still and that left an overall good impression with me, i was very invested in the story, despite its shortcomings.
