A bad narrator can definitely kill a books enjoyment. Bill Bryson is pretty bad at narrating his own books, the versions I have are narrated by William Roberts and are much better. But, Michael Palin reading his own books is excellent.What narrators are your favorites?
Best narrators?
Nigel Planar narrating Terry Pratchett's Discworld, Tony Robinson is pretty good for the abridged versions.
Stephen Fry. Baaaaaah!
Heath Miller is excellent with the He Who Fights with Monsters series.
Wil Wheaton - Surprisingly good with audiobooks, especially The Martian.
Ray Porter doing the Bobiverse series
Luke Daniels doing the Magic 2.0 series.
Aaaand finally, I'm going to recommend an audiobook production company. Soundbooth Theatre. They are superb. The narrators are some of the best out there imo. Especially Jeff Hays and Annie Ellicott. They regularly stream their recording sessions as well so you can watch Jeff crack up in the middle of a line as he's cold reading it. We also try and make him laugh in the comments on youtube. Some of their most popular productions include Dungeon Crawler Carl, Everybody Loves Large Chests, The Feedback Loop and Monster Hunt NYC.
