Guidall picked up The Dark Tower series after Muller's death and he was very, very good. But to me Muller was the narrator for that specific series. He was the voice of The Dark Tower.
A narrator change for a long running series is jarring - and it goes to the performance I mentioned earlier - the same characters can come across differently because of it
Who are some of your favorite narrators?
Mine are RC Bray, Luke Daniels, MacLeod Andrews, Angela Dawes, Ray Porter
