A 50-min movie tells a very consistent story that's easy to follow, there's no irrelevant info and the pace is just right. This isn't something made for the sake of fujoshis but rather a heartwarming story that you definitely can and should watch with your family or friends. The way the social issues are addressed is quite a rarity in Japanese media (not so much in the West maybe but still) so I'm pleasantly surprised to find a work like this.
The visuals and the lighting are really good and well-thought, almost surpring for such a low-budget project. My only problem was the acting that seemed a bit dry here and overly sentimental there - reminded me of older cheap dramas full of overacting. The story is also not that interesting because you can predict literally half of it from the start, but it still has a hearwarming message so you can easily ignore those drawbacks.
Unfortunately, I don't think I'd be motivated enough to ever rewatch it alone, but I might show it to my family or friends who don't enjoy your average BL content.
