Why, god, why? Why do you hate me?

Why are you taking Sweeney Todd, one of the boldest experiments and greatest achivements of Stephen Sondheim (an artist I identify with and am thankful for year after year and first among his generation) and putting it in the hands of Tim Burton and Johnny Depp?

Burton is a "director" whom I loathe with the heat of a thousand suns; Depp is an actor who is completely wrong for the part and whose vocal skills are a complete question mark. So really: Why, god, why? Did I desecrate a shrine or something?
