Story - 8/10
In my opinion, the story and concept were beautifully written and thought of. Especially considering that the entire story had to fit into a 25-minute episode. Two friends who are separated by distances far away, and try to keep in contact with each other. And as the distance grows, it grows more difficult, messages taking longer to go through. There isn't much more to say on the story due to the episode again- being only 25 minutes.
Art- 4/10
Unfortunately, comparing to other anime's art styles at the time it had come out, it was a poor art style. Though the art style did work well with the space battles, I'm afraid that's all. It was at the point where the characters looked very different depending on the angle, and it was hard to decipher the character's emotions though they looked like it was supposed to be clear on their face. Overall the art style really isn't that great.
Sound- 7/10
The sound was quite redeeming in the story. The AI's voice was played well, along with the electronic and mechanic noises such as the blasts and beeping. Along with sounds from the character's surroundings were played quite well. The thing about the sound though is that with the characters, along with the animation, it's hard to tell their emotions.
Character- 6/10
Considering the 25-minute span, it's obvious we weren't going to go too deep into the characters. It's quite impossible. So within the span of 25 minutes, we don't get much of the character's character. And like said before, it was hard to decipher if there was any, emotion. Though it is mainly shown through the actions they make that show how they are feeling.
Enjoyment- 8/10
Hoshi no Koe has such an interesting concept. Could it have been portrayed better? Yes. But that doesn't mean that it hasn't already been portrayed well. It's a beautiful and emotional story that I did like.
Overall- 6/10
Overall, all things considered, I'd give the OVA a 6/10. Like said earlier, the OVA portrayed the story well, though the animation and character are lacking. I would suggest this to a friend if they were looking for a quick watch, considering it's only 25 minutes.
