1. they miss the whole thing that made Monogatari a cult anime: the mystery, the puzzle, the interesting interjections. There is none of that. It is all so boring that you feel the dread and want for it to be over
2. All the "reveals" are already well known by both us and Araragi from the previous installments but he seems to have forgotten them for no reason
3. The ending made absolutely no sense and made Araragi way too powerful
In a word the show looks like a bad fanfic . There are times when story tellers lack inspiration and try to fake it. They produce a lot of low quality material like this one. A similar thing can be said for Stephen King recent novels.
Basically if you are the person that accepts a show only because it has you favorite characters and is created by the same creators as the previous work you may like this. But if you are someone that cares for quality and asks questions and wants something actually interesting you will find it as a way too long filler. If this would have been one episode 20-30 minutes I would have been ok with it. But stretching it to 6 20 min episodes is way too much for a filler.
