  • Spock must return to the past to save himself as a child.

    This is easily the best episode of the animated series and sometimes even makes those lists in magazines and websites of the top Star Trek episodes of all time. And why not? "Yesteryear" ties directly into three episodes of the best episodes of original series ("The City of on the Edge of Forever", "Amok Time", and "Journey to Babel",) guest stars Mark Lenard, who reprises his role as Spock's father, and is the only Star Trek episode to deal with an issue that anyone who has ever owned a pet cares greatly about. The episode, written by D.C. Fontana, has great pacing and dialogue and features some excellent voice acting by Leonard Nimoy.
