"Batman v Superman: Dawn of Justice" endured a lot of criticism, for its grim tone, for its plot and for the design of Doomsday, a monstrosity created with Kryptonian technology that combined Lex Luthor's blood with General Zod's DNA. While Doomsday served the same purpose in the film as he did in the comic books -- he killed Superman, at least temporarily -- what audiences saw on the screen looked a lot different from the DC Comics source material.
