[Akito Kinomoto]

All female cast and yuri/shoujo-ai are not mutually inclusive. Likewise, harem and "all girls" aren't completely divorced either (Iono the Fanatics comes to mind). But anyway, the gender of the characters involved in a romance or anything doesn't really matter to me. There used to be a time long ago when I would gravitate toward a series just for featuring girls draped over each other (I'm male and I find it hawt, okay?). These days I just leave my judgments for the work itself. If we're discussing pure aesthetics though then yeah yuri and/or all-female cast is much more pleasant to my eyes (and doujin fodder!) even if the show itself is insufferable to my enjoyment.
