I "purchased" Star Wars, and finished listening to it yesterday.
Sound effects were good. Score was good. It was neat to hear how the scenes were fleshed out, and how the gaps were filled in for the stuff that happens off-screen. Now, how much of that was Brian Daley, and how much was Lucas, I don't know. Guess I'll need to read the novel again to find out, if I'm interested (which I'm not).
But some of the voices were just too far off. The guy playing Ben, especially (and he has a ton of dialogue, too, which doesn't help). After seeing the movie literally hundreds of times, and memorizing not only the lines, but the tone and inflection, it's a bit jarring to hear someone else's take on it.
It was also a little annoying to hear the additions to the on-screen dialogue. What I mean is, the stuff that they had to put in there to describe the actions that we see on screen. For example, instead of just seeing Luke turn his lightsaber on for the first time, Ben has to mention what's happening, for the radio audience: "Hit that button, and the blade will materialize out of thin air." I understand it--Star Wars is a very visual movie, and the stuff that viewers take for granted might not make sense for someone who was only listening, hence the additional explanations, but that doesn't mean that it's not a little unnatural-sounding.
I'm glad to have heard it (I have been curious about the radio dramas ever since hearing about them years ago), but at this point I'm not sure I'll bother with the other two. On one hand, it would go against my completist nature to grab the first and not the other two. Plus, I'd really like to hear John Lithgow's take on Yoda. On the other hand, there are apparently some problems with the copy of Empire. Plus, they're huge and long (twss), and given how apathetic I am about the first one, I'm not sure I'd enjoy the other two enough to really make them worth it.
Anyway, no matter what I decide, I'll keep everybody (meaning Jesse) apprised of the situation.
