If not for the Super Saiyan 4 I'd say Dragonball GT, but aside from that, I can forgive the prequels, but The Clone Wars is my eyes is definitely non-canon. So is TFU not just because it is shit but because of the reasons Yahtzee highlighted: It's hard to believe that people didn't believe in the force in A New Hope if this one guy was taking down Star Destroyers with it a few years before.
