Honestly, the last two episodes weighed heavily on my score, because really, they were the only good ones.
It was certainly interesting to see the various pins which each episode adds to the overall fabric of the saga, but they aren't all that necessary, and the mysteries itself weren't interesting at all. The impression I get is that Nisio needed to tell the Koyomi Dead tale in some way to create a cliffhanger for the series finale in Owari, but had not enough material to stall us for a whole book, so his ingenious decision was to write several unrelated stories, since by now he is so stablished as a cult writer that he can do anything he wants because a big part of his fans is certain to swallow it.
The only thing it added was a bit to Sengoku's character (which didn't really made me like her), but Owari did enough to make Koyomi unecessary. Despite having all (most) these characters close to my heart, I really prefer when they do things in order to advance the plot in some way instead of just chatting around, because since SS these conversations unfortunately became more and more lacking of a subject.
I don't believe he is just milking it at this point, he seems to really care about those characters, but some aspects of it are obviously just to beat around the bush. Now that we are done with the first part of the story, I really don't know what to expect of this new age of the Monogatari series.
