The visuals are plain at best and character animation is wonky, with jerky movements and frequent drawing errors. [...] Omamori Himari is an awful anime without a doubt.
Not sure if we can trust Nova on this, or anyone really: Aroduc rejected Kimi ni Todoke based on "artistic demerits" (!). The accompaining screencaps look nice. One of them would be not out of place in Haruhi. But then, "jerky movements" are difficult to illustrate with mere screencaps.
