I will say that voice acting would have totally fit a cheesy animated SW adaptation. I’d watch the shit out of that. But it’s tough with the radio drama because so much of it is left up to the imagination so obviously a lot of the memories of the film is getting in the way (and radio acting is a lot different than film acting).
There’s probably an argument to be made that the worst casting decisions were Hamill and Daniels. If not for them, it would have been a totally different experience and possibly much easier to reconcile.
