Not the most involving of titles, the story line isn't too bad.
Billed to be more like a "Sci-fi/Spagetti Western" than just about anything else. It pretty much lives up to the hype.
They could have done a few more things that would have made it much better but I don't write and produce anime.
Over at Anime News Network the fans give it a solid 6.5
At Anime On DVD the last two discs aren't reviewed but discs 1 through 4 rate a C to a B

Personally I could say about a 7 but I like spagetti westerns.
There were some pretty bad episoeds here and there but overall it was rewatchable and kind of fun. The first couple DVDs were awsome.
It had a tendancey to change it's story line as it went on like they knew where they wanted to go but not how to get there.

I've seen the whole 24 episode set for around $50, not a bad deal for almost 10 hours of entertainment.

The OVA is out from Funimation.
It's kind of a 5.5.
