I really enjoyed this one too, I think it’s an essential watch for Haruhi fans, or more specifically, Nagato Yuki fans, but not really for anyone else.

yes it does finish a bit weakly and on a mild cliffhanger because, as is unfortunately common, it’s only a partial adaptation roughly covering the events from 5 volumes of a 10 volume series. so there’s a fair bit more to read if you want to continue it but they have cut out a lot of extra fluff and a bit of bloat from the manga. they did a fairly good job streamlining the manga into a 16 episode series. a full 2-cour would have been too long and drawn out, a standard 12eps would have been too short to cover both the light hearted SOL rom-com fluff and the more serious arc they adapted very well that crosses it into the main Haruhi universe.
