What are some good, long anime? By long, I mean more than two cour.
I've been watching one-cour anime a lot recently and I feel like those shows are usually too short for the viewer to get attached to and invested in the characters.

So I'm looking for longer shows now (but good ones, not long for the sake of long).
Something like HxH, LOGH or even Code Geass, for example. Any ideas?
