Seeing as I haven't watched it yet, I can't personally comment on the Black Rock Shooter OVA. The title character looks pretty cool though.
I heard it wasn't all that good though. Great fight scenes, but poor storytelling and character development. Again, that's just what I've heard.
But you know, I don't know what people were exactly expecting considering what the source material was. It's an OVA based on a Vocaloid song based on a character drawing. Not exactly all that much to really work with here.
