One episode at a time, very boring. If you are thinking about watching this you are probably not looking for aome great work anyway, but this is bad even for an out-and-out action anime.
O.K., needed to be better for the action sequences. They are over very quickly and leave you wanting more. Sadly and no stage is there a proper fight sequence to enojy properly.
The music is actually pretty good; the voices are mediocre at best. The english voicing is better in my opinion. If you are going to watch it, watch it dubbed.
Very 1D, no development is made at all, the side characters who are introduced do not have enough involvement and it gets to the point that you just don't care
Avoid, unless you have played all the games and are bored with nothing to do
