You were expecting this to be a shitty fanservice show?
But yeah, the animation never get much better, although that's one of the fuckups Artland did with the show (among that they toned down the violence and messed up the continuity of the manga). Watch the animu after reading the mango if you really, really want to see it animated. Although it will make you cry and/or rage.
"Skip the animu, read the mango" never rang so true.
