"It's Sweeney Todd now, and he will have his revenge."
This just came to mind on heromachine. Another one of my favorite horror killers. I've seen the 70's opera version with Angela Lansbury as Miss Lovett. Then I saw the Tim Burton version, with Johnny Depp as the title character. So this one here is kind of a mix between the two that I've seen. Also, in the original story, Sweeney was not a sympathetic character, looking for revenge against Judge Turpin for ruining his family. He was a greedy thief, who would knock out wealthy customers with his sliding chair, then cut their throats for their money.
EDIT: With Heromachine.com updated, I changed his weapon to an actual razor.
