The Trekzone Review

Hello Klingons, how are you? Welcome to Star Trek!! The world’s most recognisable villian gets their debut in this episode – tucked away in the last quarter of the first season. The events in this episode would carry weight for the remainder of the series… and who can forget Kor?

This is one of the few truly superb episodes of season one.
