American audio drama has been very slowly rebuilding itself ever since the massacre that was the coming of television, and over the past few years a critical mass has started to form. Locke & Key is an ambitious epic, a thirteen-hour-plus adaptation of Joe Hill & Gabriel Rodriguez’s graphic novel featuring a massive cast and co-produced for Audible by Audio Comics and Final Rune productions. I haven’t actually read the graphic novel, so I’m forced to judge this entirely on its own merits. It can best be described as an adult take on a YA fantasy concept, using magic and the supernatural to tell the story of a family haunted by bad decisions made in the past and by the ones they keep making. Parts of it are whimsical, other parts are very sad, and the overall effect is very powerful indeed.
