IMO, yes, in a lot of areas, Kagihime does seem to be really lacking compared to the other shows this season.
But for me, I find myself enjoying it though, mainly because of the setting and the BGM(one of the best I've heard recently). I also kinda like seeing the character interactions, eg. Kiraha vs Arisu and Kiraha's yuri stalker.
Well, I guess this show is just better enjoyed without giving much thought towards it. We've already have Otome to debate on
