The look, story, direction, characters are all set-up wonderfully (or so it seems from the trailer) but I am quite underwhelmed by Johnny Depp's singing. Granted it was just a few seconds so perhaps his singing is going to be good. But if he's going to be singing that weakly and doing more half sing/half talk through all the songs it will be a major downer for this film (it is based on the musical afterall). The role of Sweeny doesn't need someone with a pretty singing voice but it does need passion and power and Depp's voice came across very weak.
Didn't he sing in Corpse Bride?
