An interesting, mysterious story that while gorgeously animated, feels more like a stand-out episode of a Sci-Fi TV series than a standalone movie.
A great wrap-up for the series ... satisfyingly rooted in a sense of reality and introspection the way a good spiritual supernatural story should be.
Mostly an OVA collection of half-episodes, except there are a few plot-critical episodes, specifically near the end. A nice breather before diving into the final seasons.
Despite (or perhaps due to) being a completely different vibe and style from the rest of the Monogatari series, this is hands down my favorite.
Very good arc here, all the good supernatural, psychological intrigue, with hardly any of the annoying ecchi aspect. Praise.
