I agree, this sort of shocked me but after careful consideration i like the idea. At first I thought to my self "oh no a rehash of the turn bad then good again story line" but i was told that this was not the main plot outline of this trilogy and that we are goi g to see the true evil natyre of the darkside and this is a quote directly from the idividual/individuals that shared this with me "you will really appreciate what vader means when he keeps saying "if yiu only knew the power of the.darkside" in tHE OT.
