I'm a big fan of The Doors and pretty much knew the story before watching this film. And yet I found Johnny Depp to be a very convincing narrator (usually I find narrators to be quite annoying in documentaries!), and the film was quite fluid and easy to watch. Some really cool footage as well! For anyone who's interested, Oliver Stone's 1992 film The Doors is a good and fairly accurate non-documentary worth watching, if you haven't seen it already.
