In 1966 World War II had ended just over 20 years ago and the victims of the holocaust were still in many peoples minds. This episode would have had more impact when shown then as it takes its roots from classic Shakespeare and fuses it with the hunting down of a Nazi war criminal and giving justice for the crimes he did during the holocaust.
Its a well acted episode and although a little slow in places could have worked on any mainstream drama show. I like it that Spock confides in McCoy when things trouble him as he knows the McCoy is Kirks best friend. Miami Vice also did a similiar episode but without the Shakespeare. Titled "Victims Of Circumstance" where the Nazi War criminal's daughter was killing surviving witnesses.
