Zod's one of Superman's more one-dimensional villains. He's not as interesting as Lex Luthor or scary like Doomsday. But Terrence Stamp's performance in Superman II was one of the highlights of that movie (I like his rant against Jor-El in Superman I). "Kneel before Zod," is one of the best lines period.
