This anime is very confusing. I heard that there's an old version to this one. The new one is pretty messed up. It's very fast-paced and it literally messed up the whole story. I can't recommend this anime for now. I'll try reading the manga though...
Story: This story is loosely based on a old chinese folk-lore 封神榜. Very past pace without context to anything. Very confusing.
Characters: ok, nothing special. None of them are all that interesting. As mentioned above, show is very fast pace so no proper character introduction or back story. Some characters just appears and then never seen again without reason.
Animation - The editing and screenplay is terrible. There is no flow. Randomly jumps from one scene to the next. Can be very confusing.
Overall - terry storyline and feels like a mad rush to do this anime. I watched the dub version and it was horrible. Sometime things didn't make sense compare to what you are seeing.
