Hitsuji no Uta is an interesting anime, and if it had more time to develop it would have been really good. The anime as it stands at 4 episodes manages to tell a good story, even though it is short. What I found cool about it was that, instead of the low budget taking away from the enjoyment, it actually added to it. The repeated images and switching between black and white and color make the anime a little more stylized, rather than hindering the interest of the story. The way they show Kazuna's attacks also adds quite a bit of tension to the experience.
Art
The art style looks good most of the time, but sometimes ends up looking a bit off from the way you see it normally. This only happens in a few scenes, and it doesn't really disturb the presence of the theme. And like I said before, the low-budgetness of the anime actually stylizes it and makes it unique.
Sound
Really, there's not much here. There's about one song plus the ending theme. The one song in the anime actually fits in most of the situations, so even though there's not a large variety, it adds a familiar atmosphere when certain events are happening.
Character
The characters weren't that developed, mostly because there wasn't enough time to get to know them all. But by the end, you have a feel for the personality and ideals of most of the important characters.
Enjoyment & Overall
I enjoyed Hitsuji no Uta quite a bit, and because it's so short, the story doesn't get distorted and twisted around until it's unrecognizable. I would recommend it to anyone; I'm sure anyone could find something to like about it. Even if you don't like it a ton, you're only with it for 2 hours of your life, so you can watch it and add it to your repertoire of anime knowledge without too much effort.
