I've been meaning to watch the Nagato series. I saw Disappearance for the first time recently too, and I was quite taken with it, although I felt I missed a lot because it was before my re-watch of the series.

I'd actually really like to read the light novels, despite all my complaints recently about such works, and whilst I found myself really annoyed by aspects of the show 10 years later, I wouldn't be absolutely adverse to watching something new with these characters... in fact, I think I'd actually quite like it.
