^yes, very. A lot of fans prefer the original, unaltered trilogy. Not just for this reason, but a long list of others, including Han shooting first in the cantina.
one way to force fit that into the story is that Anakin died at the end of Episode III, from then on he was Darth Vader, as Obi Wan pointed out and the force ghost was Anakin not Vader (despite Vader finding some kind of redemption in the end)
Till now Lucas had the last say in everything Star Wars, and that was not necessarily what the universe or fans deserved. And if you look at his interviews across the years, he never had a clear picture of what exactly the story was going to be. Luke and Leia were once not brother and sister, he kept going back and forth on how many stories he had planned, whether it was 6 or 9 or 12... R2 and C3PO needed memory wipes to fit into the plot. At the end of Episode I, the Star Wars databank (whole thing is offline now) had a bio of Amidala Padme, and apparently she lived till old age as a monk on Naboo, this was changed by the time Episode II and III released. The prequel trilogy was great, still the changes to the original story were not necessary. Thankfully, the property is with Disney now, and acc to me, its in good hands because of JJ Abrams, though there are jokes about cheese and lens flares going around. There is some indication that Disney Intends to release the original, unaltered trilogy on Blu-Ray as a lead up to Episode VII. So that is something to look forward to.
