First off, the new Kizumonogatari trailer is amazing; I patiently await all three parts.
The first episode of Owarimonogatari was a nice change of pace, being framed mostly within the one classroom while transitioning nicely between the past and present. The visuals were nice too. I particularly enjoyed the scene when things fall apart during the class meeting; I felt it clearly conveyed the feeling of Araragi being unable to control the situation while it occurs almost as if disconnected him and Sodachi. This episode as whole works as a self contained vignette with its clear message and swift resolution but still connects to the main story and Araragi as a character, showing the changes he has gone through while we remember that he is also going through more changes, or rather has to change.
Excited for the rest of Owarimonogatari and wherever it leads (although I have spoiled myself on the whole series, I will just forget about that, or rather I just will not think about it).
