I have 3 rather distinct "ratings" I like to give anime.
MOST anime I watch the entire way through without stopping, this is mostly due to psuedo-OCD where I MUST know what happens.
There are a few series I couldn't complete if I was at gunpoint, to date there's only been 2 series that falls into this category, the names of which I forget, probably memories that are being repressed.
Kyouran kinda falls in the third. I certainly don't think it's "too bad to even look at". But I got to about episode 5 and don't care to keep going.
