I started watching Bakemonogatari and it's pretty damn good.
Yeah it gets better as it goes too.
My main surprise is that Nadeko, is a very uninteresting character and not exactly a good arc when she becomes a focus. I personally hated her because she wasn't just fanservice, she was so detached from relevance to other characters, araragi especially, and that her entire arc was rather boring outside of the Kanbaru scene.
HOWEVER in this season her arc is probably the best one by far and its REALLY well done.
If I could relate this in terms most everyone would understand: Basically yamcha got another shot and he was fucking epic somehow.
