This is my first review, so... Well. Here I go.
Really... Before watching BRS, I was expecting something, like... "Pew pew pew fight fight". Indeed, I didn't receive it. It was just a slice of life. And guys, I tell you. The OVA is good, it just got the wrong public with that trailer. I mean, everyone was expecting something else, like Black Rock Shooter fighting against Dead Master and all. But, well, you see, they got... That. A slice of life.
Story: 7
The story isn't bad, it's even good, I tell you. For a slice of life, it's great. But I can't rate it with more than 7. Simply because it could have something more.
Art: 9
The art was great, but it wasn't actually "Godlike". Well, I suppose you can't have a good OVA just because of the art, right? After all, once the animation was the ones of an OVA, it had to be great.
Sound: 10
The soundtrack of this OVA is AMAZING. Really, it couldn't be better. But, like the art, it can't make a good OVA alone.
Character: 7
How can I put it? Well... The characters didn't catch my eye. They were just "normal". It's not like if I didn't like their personalities, they simply weren't "FUCKING WIN". Something like this.
Enjoyment: 7
Many people won't enjoy it, because of the trailer. If you watched the trailer and you're waiting for fight and all, then you won't enjoy it. But, if you like a slice of life with those typical problems of an adolescent (feeling like if you've been forgotten by your best friend), then you'll enjoy it.
Overall: 8
Well. The anime itself is good. Very good. As I said before, it just had the wrong public. Again: IF YOU ARE EXPETCING SOMETHING WITH (many) ACTION SCENES, THEN DON'T WATCH BLACK ROCK SHOOTER! Unless you like few action scenes and lots of slice of life.
