Well put, Gaffer Tape. That's exactly how I feel. Saying Anakin died in Episode III ruins everything. You're saying that Vader is a completely different character. If that's true, why is Anakin the force ghost? Anakin never redeemed himself then. Vader saved Luke, Vader killed the Emperor. Why reward a personality that did nothing?

Instead of a story of redemption, we have one of some guy who has split personallities that can finally be good after his death. Absolving Anakin of all wrong doings makes him the utterly boring character we had in the prequels. There's nothing left if you ditch that.
