I agree, dialog, action, and it's lack in some point. Everything perfectly calculated.
I know a lot of people didn't really like the story, but personally, it's a one of a kind Katana Story.
The best thing in fact was the relationship and loyalty, and following the path to complete her revenge.
That story is a lot more romantic than most people notice, which is sad because so many people watched it for the witty dialogs and the action so they completely and blatantly missed the romantic atmosphere nearly in every episode.
And the final episode had the culmination of the romance that so many viewers completely missed.
I also wait for Kizumonogatari, from Bakemonogatari and Nisemonogatari you can nearly easily figure out the relationship between Araragi and Hanekawa and also Shinobu and Araragi, but that is all due to what we hear and read believing in the accuracy of given information, and as we know, we know very little about that.
I'll probably re-watch Bakemonogatari and Nisemonogatari (the latter for lulz mostly but who wouldn't?) right before watching Kizumonogatari.
