Sweeney Todd and the demon barber of Fleet Street is a good musical if you don't mind seeing life-juice and deformed people. *singing the soundtrack and watching my brother becoming more and more terrified of me* Also, Sweeney isn't a bad guy, he's just a misunderstood sad, depressed dude who's been plotting revenge for three years while in jail and gives the closest shave in existence.
