Doragun Boru and Z. All the Zeta movies, TV specials and OVAs but only one DB movie (according to MAL - don't even remember it) and the public service announcements.
GT not seen any episodes and Super seen like 10-20 at most I think, plus Battle of the God's.
I blinked though, so I've seen 0 episodes.
Oh yeh I've watched Kai up to Trunks vs Freeza - actually I got to Vegeta vs Semi-Perfect Cell, but then got bored because that just drags out and it'd lost the new Yamamoto score, which was part of why I watched Kai (plus just to rewatch the Vegeta/Freeza sagas, but then I carried on for a bit since the series had momentum).
