I'm a sucker for those shows, Haruhi and K-On! Probably because I rarely communicate with their fanbases so I really have no true scale or perception of the hype. They're just cute simple shows that detract from the real world by being like the real world.
Didn't the director for Dead Leaves work a bit with TTGL. It would explain the drills. I have not seen too much of Ghost in the Shell. Way too many animes. I'm getting some sort of cranial mushroom cloud from thinking about it all.
So instead I play Portal. It's freaky.
