Epic fail, that one. I've loved the musical since the 1970s and there are a couple of things majorly wrong with the Burton adaptation. Sweeney Todd is played by a baritone! Not someone trying to sound like David Bowie. If you can get a copy of the filmed stage version starring George Hearne and Angela Lansbury, you can track how much of a difference having a solid baritone makes. It takes the character to a new level of darkness.
