I do not have a very deep review but this is the best I can describe it. This seems like the work of someone who really has so much to tell but just does not enough resources to tell what he/she wants. Honestly if a series of 12 episodes is made on it (with a great budget) then it could be amazing. The story is amazing but the time it gets to tell it is just not enough. The art style as well as the music is amazing. I think most people disliked it because of the fact that cg is used when it is probablyone of the best cg I have seen by now. I might as well say cg made it better but people conditioned to 2d anime will just not like it.

The type of people who like this are star wars fans or galactic heroes fans, basically people who like hi-fi future stuff with a little sad drama (star wars r.o.t.s). If this describes you WATCH IT.
