Yeah, Han and Darth are the most jarring to get use to. But in a way I really like the different actors portraying them. I like Darth Vader, because he seems like he is right out of an old science fiction radio serial. He may not be James Earl Jones, but if you unlearn all you have learned and let the story take you as if for the first time, Brock Peters really does a good job of the stereotypical evil menacing villian, which is what Vader was originally. I always felt the radio drama did a great job of taking Star Wars back to its roots without all the baggage. It is something plain and simple you can enjoy, even if you havent seent he movie. I always felt bad for people who never read LOTRs until the movies came out, because instead of getting to discover and imagine all these fantastic places, you only get to see what others imagined them to look like. For many people Frodo will always be Elijah Wood. For me, Elijah Wood merely portrayed Frodo in a movie at one time. With the SW Radio drama I like to try to forget everything and reimagine it all as if for the first time. I like to force myself to think of Vader more as how he appeared in the early conception art. I am not sure why I like to do this, but I find it very refreshing. Another thing I like about the NPR series is the catchy episode names! Aren't they great?
