Thanks to the podcast "A More Civilized Age", I finally watched "Crystal Crisis on Utapau", which is one of the never-completed story arcs from the The Clone Wars when it was first cancelled. A version of it is available on Youtube, and it's a remarkably fun and surprisingly emotionally-resonant story. Anakin and Obi-Wan actually talk about their feelings! Not for long, but still! It's full of witty banter as well. Much recommended although it looks pretty weird.
