I've never actually watched that anime (The Bakemonogatari series one)
What's it about actually?
It's a monster story. Not the omghorrorD: story, but oh super natural shit is in my town and I won't stand for that, type of story. Plus harem and romance with ecchi, with visuals to die for and caricatures so vivid it's like they were there sticking staplers into your mouth. So it's worth it.
:I Well then I might give it a watch, I don't watch supernatrual anime but when I do, I go for the all out ones.
