I am for giving the Anime a well deserved 10/10 although the storyline can get a bit confused at times like with the alien combat dudes.
The visuals and attention to detail are a joy to watch. The sound track and FX are really well implimented. You will love Shiro and Kuro's adventure in treasure town.
This Anime is a must if you enjoyed FLCL style of story.
