Maybe before checking out the prequel you should watch the other sequels. Hanamonogatari, Tsukimonogatari and Owarimonogatari. You have a long way to go.
I'm not really excited for Kizumonogatari, mainly because I don'tgive a flying fart about Koyomi. And it's pre Senjougahara, Hachikuji, Kanbaru, Ononoki, Ougi. Basically it's before any of the interesting characters appeared.
