I'm not sure about the low reviews, but I can say one thing for sure. This anime is one of the best I've seen.
First off, the art and story. It's both pure and original. The story is something unlike anything I've seen. It's true that I only watched it due to it being recommended from Eden of the East, but even this is a completely different turn from that. You have a generated currency which is pretty much endless, if used right. You have to fight in Deals to gain more money and to stay in the world. If you go Bankrupt, you're kicked out of the world and all your money is taken from you. From the point of another person, it would seem plain. It's far from that, very far from plain. It's the essence of a masterpiece.
The soundtrack was something that I picked up on right after the first episode. It brings the mood to the anime. It strikes it at the right time. It's beautifully made and one of the best I've heard. As for the OP and ED, they're both great. Now, for the background noises and such, they're accurate according to anything else. The voices fit within the duels and act funny if enough is spent. It seems to make sense.
Overall, a stunning 10/10. This is a must watch for an anime enthusiast. You're missing out on a great thing if you don't watch this.
