After watching season 6 with the Yoda Arc, the Clone Wars just has to be edited into a trilogy. That Yoda Arc, is everything I loved about Star Wars, and everything that the PT lacked. Our (star wars fans) prequal trilogy is there for the taking in the Clone Wars episodes. Now we simply need an editor out there with the Force guiding them to create the prequel trilogy we have all been longing for.
Nighsisters - Mandalorians - Maul and Savage - Mortis - Yoda: These arcs should provide enough for a trilogy.
