Mamoru Hatakeyama is one of the top directors working in anime today, so dismissing his work as "lol DEEN" is rather unfairly prejudiced.
Yeah. Just saying stuff such as Log Horizon and Umineko looked particularily weird at times, mostly when the characters would suddenly go off-model for reasons (often with comedic intent, I think), but Higurashi fared better because the graphical inconsistencies made sense with how the cast would start whimsical and endearing, but then would begin acting weird and eventually would break down psychologically (often with grisly repercussions for the rest of the cast).
